副反応生成物の中から目的物質を単離することは
不可能に近い努力を必要とする。 The most common conventional method for synthesizing biphenyl ether is the Ullmann reaction, but due to the harsh reaction conditions, the co-existence of many by-products is unavoidable. ,
Therefore, the yield is generally low and furthermore, purification is difficult, and for this reason, it cannot be said to be an appropriate synthetic method for producing complex compounds. In particular, it is even more difficult to create an ether bond at the ortho position of the phenol in a substance with a complex structure and asymmetric carbon, as in the present invention, and even if the reaction progresses, only a few %, and it requires almost impossible efforts to isolate the target substance from among the large number of side reaction products.

る。 As an improvement method to further advance the Ullmann reaction, it is possible to increase the reactivity of the halogen atom of the compound to be combined with the hydroxyl group of phenol. To do this, it is necessary to add an electron-withdrawing group (such as a nitro group) to the ring. It is to add .

After separating the deposited precipitate, saturated aqueous sodium bicarbonate was added to the solution and the mixture was stirred to separate insoluble matter and separate the mixture. The obtained organic layer was washed with saturated brine, dried over magnesium sulfate, and the solvent was distilled off under reduced pressure to obtain 2.33 g of a slightly yellow oil. When left to stand, the oil crystallized and recrystallized from benzene-n-hexane to give slightly yellow sand-like crystals (melting point 97-100°C).
