본 발명은 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨 삼수화물을 경제적 방법으로 대기중에서 고순도 고수율로 제조하는 방법에 관한 것이다.The present invention relates to a process for producing 4-amino-1-hydroxybutylidene-1,1-bisphonic acid monosodium trihydrate in high purity and high yield in air in an economic manner.
골다공증 등에 탁월한 효과가 있는 것으로 나타난 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 또는 이의 염은, 미합중국 특허 제 4,407,761호, 미합중국 특허 제 4,621,077호에 따르면, 다음과 같은 방법에 의해 얻어진다.4-amino-1-hydroxybutylidene-1,1-bisphonic acid or salts thereof that have been shown to have an excellent effect on osteoporosis and the like, according to US Patent No. 4,407,761 and US Patent No. 4,621,077, Obtained by
먼저, 아미노카복실산을 포스폰화반응을 사용하여 비스포스폰화 한 다음, 반응 혼합물을 가열하면서 비산화 강산, 바람직하게는 진한 염산을 가해 급냉시킨다.그리고, 이 때 형성된 인 중간 생성물을 최종 생성물로 가수분해 함으로써 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산을 제조하게 된다.First, the aminocarboxylic acid is bisphosphonated using a phosphonation reaction, and then quenched by addition of a non-oxidizing strong acid, preferably concentrated hydrochloric acid while heating the reaction mixture, and the phosphorus intermediate formed at this time is hydrolyzed to the final product. Thus, 4-amino-1-hydroxybutylidene-1,1-bisphonic acid is produced.
또한, 미합중국 특허 제 4,922,007호에 따르면, 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산의 제조시, 비스포스폰화 반응 혼합물은 균질하지 않고 부분적 응고가 발생하였는데, 이를 해결하기 위하여 용매로 메탄설폰산을 사용하였다. 또한 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산을 분리하여 일나트륨 형태로 전환시키는 추가의 단계를 줄이고, 1단계로 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨 삼수화물을 제조할 수 있도록 하였다.In addition, according to US Pat. No. 4,922,007, in the preparation of 4-amino-1-hydroxybutylidene-1,1-bisphonic acid, the bisphosphonated reaction mixture was not homogeneous and partial coagulation occurred. Methanesulfonic acid was used as a solvent. It also reduces the additional step of separating 4-amino-1-hydroxybutylidene-1,1-bisphonic acid and converting it to monosodium form, and in one step 4-amino-1-hydroxybutylidene-1 , 1-Bisponic monosodium trihydrate was prepared.
한편, 미합중국 특허 제 5,019,651호에 따르면, 가수분해 과정에서 농염산이나 물을 사용하지 않고 pH가 조절된 물을 사용하여 고가의 유리장치를 스테인레스 스틸로 대처가능하도록 하였으며, 이에 따라 압력제한성이 사라져 가수분해 과정에서 압력을 가하여 가수분해 시간을 단축할 수 있도록 하였다.On the other hand, according to US Patent No. 5,019,651, the use of pH-controlled water without using hydrochloric acid or water in the hydrolysis process enables expensive glass apparatus to cope with stainless steel. Pressure was applied during decomposition to shorten the hydrolysis time.
하지만 최근까지 개발된 방법으로 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨을 생산하는 경우, 반응 중에 삼염화인을 넣는 과정에서 염화수소가스가 대량으로 발생하여 작업자의 안전성을 보장 하기 힘들며, 비교적 고가의 아인산을 사용해야 한다. 또한, 방응 도중 계속해서 질소기류 중에서 반응을 해야하며, 공기 중에서 반응시키면 순도가 낮아져 정제과정이 필요하게 되고, 이로 인해 수득량이 현저히 떨어지는 문제점을 들어낸다.However, in the case of producing 4-amino-1-hydroxybutylidene-1,1-bisfonate monosodium by the method developed until recently, a large amount of hydrogen chloride gas is generated in the process of adding phosphorus trichloride during the reaction, and thus safety of workers. It is difficult to guarantee this, and relatively expensive phosphorous acid should be used. In addition, the reaction must be continued in the nitrogen stream during the reaction, and when reacted in the air, the purity is lowered, the purification process is required, thereby causing a problem that the yield is significantly reduced.
이에 따라, 경제적인 문제점이 있어 대량으로 생산하기 곤란하다. 또한, 대량 생산할 경우 제품의 순도를 보장할 수 없으며, 정제 과정을 거치게 되면 수득량이 현저히 떨어지게 된다는 문제점이 있다.Accordingly, there is an economic problem, it is difficult to produce in large quantities. In addition, if the mass production can not guarantee the purity of the product, there is a problem that the yield is significantly reduced through the purification process.
따라서, 본 발명의 목적은 종래에 비하여 대량생산이 가능하여 경제성 있고 안전하면서 수율과 순도가 높은 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨 삼수화물의 제조방법을 제공하는 데 있다.Accordingly, an object of the present invention is to provide a production method of 4-amino-1-hydroxybutylidene-1,1-bisphonic acid monosodium trihydrate, which is economical, safe, and has high yield and purity compared to the prior art.

그리고, 상기 반응은 공기 중에서 수행할 수 있다.In addition, the reaction may be performed in air.
이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명에서 먼저 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산을 제조하기 위해서는, 물과 메탄설폰산 혼합용액에 감마-아미노부틸산을 용해시킨 후 삼염화인을 넣어 반응시킨다. 그런 다음, 반응물을 냉각하고 삼염화인을 넣고, 추가로 메탄설폰산을 더 넣어 반응시킨다. 반응이 완료되면, 물을 넣고 환류 냉각한 후 감압농축한다.In the present invention, to prepare 4-amino-1-hydroxybutylidene-1,1-bisphonic acid, gamma-aminobutyl acid is dissolved in a mixture of water and methanesulfonic acid, and then phosphorus trichloride is added to react. . Then, the reaction is cooled, phosphorus trichloride is added, and further methanesulfonic acid is added to react. After the reaction was completed, the mixture was poured into water, reflux cooled, and concentrated under reduced pressure.
한편, 다른 방법으로는, 물과 삼염화인을 넣고 반응시킨 후 감마-아미노부틸산을 용해시키고, 삼염화인을 넣어 반응시킨다. 반응이 완료되면, 진한 염산을 넣은 후 환류 냉각하고 감압농축한다.On the other hand, after water and phosphorus trichloride are added and reacted, gamma-aminobutyl acid is dissolved and phosphorus trichloride is added and reacted. After the reaction was completed, the mixture was added with concentrated hydrochloric acid, cooled to reflux, and concentrated under reduced pressure.
이렇게 감압농축시킨 후 물을 넣어 희석하고 아세톤을 넣어 냉각방치하면, 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산이 얻어진다.After concentrating under reduced pressure and diluting with water and adding acetone and leaving it to cool, 4-amino-1-hydroxybutylidene-1,1-bisphonic acid is obtained.
이 과정에서 아인산 대신에 물과 삼염화인을 사용하므로, 반응이 격렬하지 않아 반응의 안전성을 향상시킬 수 있으며, 전체 반응에서 선행기술에서 사용한 질소기류를 사용하지 않고 공기중에서 실시하고, 고가의 아인산을 사용하지 않아 합성원가를 줄일 수 있다.In this process, water and phosphorus trichloride are used instead of phosphorous acid, so the reaction is not violent and the safety of the reaction can be improved, and the entire reaction is carried out in air without using the nitrogen stream used in the prior art, and expensive phosphorous acid is used. By not using it, synthetic cost can be reduced.
본 발명에 따르면, 이렇게 얻어진 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산을 물에 용해시키고, 수산화나트륨을 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 몰량의 0.9∼1.0배를 넣어 서서히 교반하면서 소정의 온도까지 가온한 후 서서히 냉각하여 방치하면, 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨 삼수화물이 침전된다. 그런 다음, 침전된 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨 삼수화물을 여과한 후 건조한다.According to the present invention, 4-amino-1-hydroxybutylidene-1,1-bisphonic acid thus obtained is dissolved in water, and sodium hydroxide 4-amino-1-hydroxybutylidene-1,1- When 0.9 to 1.0 times the molar amount of bisphonic acid is added, the mixture is warmed to a predetermined temperature while gradually stirring, and then cooled and left to stand, whereby 4-amino-1-hydroxybutylidene-1,1-bisphonic acid monosodium trihydrate precipitates. do. The precipitated 4-amino-1-hydroxybutylidene-1,1-bisphonic acid monosodium trihydrate is then filtered and dried.
이 과정에서 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 몰량의 0.9∼1.0배의 수산화나트륨을 넣어 반응시킴으로써, 선행기술에서 용액의 pH를 4.3으로 맞추거나 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산의 몰량과 동량의 수산화나트륨을 넣는 방법보다 순도를 높이며, 수산화나트륨을 넣은 후 용액을 가열하였다가 서서히 냉각하는 방법을 이용하여 수득율을 높일 수 있다.In this process, by adding 0.9 to 1.0 times the amount of sodium hydroxide of 4-amino-1-hydroxybutylidene-1,1-bisphonic acid in the process, the pH of the solution in the prior art is adjusted to 4.3 or 4-amino- The purity is higher than the method of adding the same amount of sodium hydroxide as the molar amount of 1-hydroxybutylidene-1,1-bisphonic acid, and the yield can be increased by heating and slowly cooling the solution after adding sodium hydroxide. have.
이와 같이, 본 발명에서는 고가의 아인산 대신 물과 삼염화인을 사용함으로써, 반응이 격렬하지 않을 뿐 아니라, 질소기류를 사용하지 않고, 공기중에서 반응해도 생성물의 순도를 보장할 수 있는 방법으로 4-아미노-1하이드록시부틸리덴-1,1-비스폰산의 일나트륨 삼수화물을 제조할 수 있다.As described above, in the present invention, by using water and phosphorus trichloride instead of expensive phosphorous acid, the reaction is not violent, and 4-amino is used to ensure the purity of the product even when reacting in air without using a nitrogen stream. Monosodium trihydrate of -1 hydroxybutylidene-1, 1-bisphonic acid can be prepared.
이에 따라, 아인산을 사용하지 않고, 반응을 공기중에서 수행함으로써, 반응시간을 줄이면서도 수득율을 높일 수 있으며, 작업자의 안전을 도모하고, 원가를 절감할 수 있다.Accordingly, by performing the reaction in air without using phosphorous acid, the yield can be increased while reducing the reaction time, and the safety of the operator can be reduced and the cost can be reduced.
한편, 본 발명에 따르면 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산의 결정화 과정에서 감압농축과 희석 단계로 총부피와 아세톤의 비율을 조절함으로써 수득율을 높일 수 있다. 그리고, 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산 일나트륨 삼수화물 결정화 과정에서는, 4-아미노-1-하이드록시부틸리덴-1,1-비스폰산을 일정량의 물에 녹이고 수산화나트륨의 양을 조절한 후 결정화 전에 용액의 온도를 높였다가 서서히 낮추는 방법을 이용하여 순도를 높이고 수득율을 증가시킬 수 있다.On the other hand, according to the present invention it is possible to increase the yield by controlling the ratio of total volume and acetone in the concentration and dilution step under reduced pressure during the crystallization process of 4-amino-1-hydroxybutylidene-1,1-bisphonic acid. In the 4-amino-1-hydroxybutylidene-1,1-bisphonic acid monosodium trihydrate crystallization process, 4-amino-1-hydroxybutylidene-1,1-bisphonic acid is added to a predetermined amount of water. It is possible to increase the purity and increase the yield by adjusting the amount of sodium hydroxide and adjusting the amount of sodium hydroxide and then increasing the temperature of the solution before crystallization and then gradually lowering it.
