Abstract

Compounds of formula 1, where R means alkoxyle with 1 to 3 carbon atoms as well as their inorganic and organic acids salts, are prepared by reaction of 3-bromo-2-hydroxy-1-propylester of alkoxyphenylcarbamic acid with 1-(2-metoxyphenyl)piperazine in an aqueous medium at ambient temperature, and/or by reaction of 2,3-epoxy-1-propylester of alkoxyphenylcarbamic acid with 1-(2-metoxyphenyl)piperazine in an alkanol medium at boiling point of the reaction mixture. These compounds display antidisrhytmic activity.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Doteraz boli známe 3-alkylamino-2-hydroxy-l-propylestery kyseliny alkoxyfenylkarbámovej, kde alkoxyl znamená substituent v polohe 2-, 3- a 4- aromatického jadra s počtom atómov uhlíka 3 až 7, a alkyl v bázickej časti je jednoduchý nerozvctvený, resp. rozvetvený alkyl s 2 až 4 atómami uhlíka. Uvedené zlúčeniny prejavili lokálne anestetickú a antidisrytmickú aktivitu (Csollei J., Beneš L., Búčiová Ľ., Račanská E., Švec P., Tumová I.: CS 276 205, Račanská E., Csollei J., Búčiová Ľ.: Čcskoslov Farm - v tlači).To date, 3-alkylamino-2-hydroxy-1-propyl esters of alkoxyphenylcarbamic acid have been known in which alkoxyl represents a substituent in the 2-, 3- and 4-position of the aromatic nucleus having carbon numbers of 3 to 7, and respectively. branched alkyl of 2 to 4 carbon atoms. The compounds exhibited local anesthetic and antidisrhythmic activity (Csollei J., Benes L., Bucciova L., Racanska E., Svec P., Tumova I .: CS 276 205, Racanska E., Csollei J., Bucciova L.: Cskoslov Farm - in print).

Podstata vynálezuSUMMARY OF THE INVENTION

Podstatou vynález sú nové doteraz neznáme zlúčeniny všeobecného vzorca ISUMMARY OF THE INVENTION The present invention provides novel compounds of the formula I which are not yet known

kde R znamená alkoxyl s 1 až 3 atómami uhlíka v polohe 2-, 3- a 4- aromatického jadra, ako aj ich soli s organickými alebo anorganickými kyselinami.wherein R is C 1 -C 3 alkoxy in the 2-, 3- and 4-position of the aromatic ring, and salts thereof with organic or inorganic acids.

Uvedené zlúčeniny všeobecného vzorca I je možné podľa vynálezu pripraviť rôznymi spôsobmi, napr. tak, že sa nechá reagovať v polárnom rozpúšťadle: a) 3-bróm-2-hydroxy-l-propylester kyseliny alkoxyfenylkarbámovej všeobecného vzorca IIThe compounds of formula I can be prepared according to the invention in various ways, e.g. by reacting in a polar solvent: (a) the alkoxyphenylcarbamic acid 3-bromo-2-hydroxy-1-propyl ester of formula II

v ktorom R znamená to isté ako vo vzorci I, s l-(2-metoxyfenyljpiperazínom výhodne v prostredí vody pri teplote miestnosti počas 24 hodín.wherein R is the same as in formula I, with 1- (2-methoxyphenyl) piperazine preferably in a water environment at room temperature for 24 hours.

b) 2,3-epoxy-l-propylester kyseliny alkoxyfenylkarbámovej všeobecného vzorca IIIb) 2,3-epoxy-1-propyl ester of alkoxyphenylcarbamic acid of general formula III

NH-CO-O-CHg-CH-ýH^ (III), v ktorom R znamená to isté ako vo vzorci I s l-(2-metoxyfenyljpiperazínom výhodne v prostredí alkanolu s 1 až 4 atómami uhlíka, výhodne etanolu pri teplote varu reakčnej zmesi počas 8 hodín.NH-CO-O-CH 2 -CH 2 -CH 2 (III), wherein R is the same as in formula I with 1- (2-methoxyphenyl) piperazine, preferably in a C 1 -C 4 alkanol, preferably ethanol at the boiling point of the reaction mixture for 8 hours.

Po skončení reakcie sa z reakčného produktu najčastejšie oddestiluje rozpúšťadlo a surový produkt sa rozpustí v zriedenej kyseline chlorovodíkovej, pretrepe éterom. Báza uvoľnená alkalizáciou z vodnej fázy sa vytrepe do éteru. Z éterického roztoku je možné bázický ester previesť priamo na žiadanú soľ a tú ďalej kryštalizovať z organického rozpúšťadla alebo zo zmesi organických rozpúšťadiel. Zo solí s anorganickými kyselinami, vhodnými pre aplikačné formy, prichádzajú do úvahy napr. hydrobromid, hydrochlorid, prípadne zo solí s organickými kyselinami napr. šťavelan, fumarát, citrát a pod.After completion of the reaction, the solvent is most often distilled off from the reaction product and the crude product is dissolved in dilute hydrochloric acid, shaken with ether. The base released by alkalization from the aqueous phase is shaken into ether. From the ether solution, the basic ester can be converted directly to the desired salt and further crystallized from an organic solvent or a mixture of organic solvents. Suitable salts of the inorganic acids suitable for the use forms are e.g. hydrobromide, hydrochloride, optionally from salts with organic acids e.g. oxalate, fumarate, citrate and the like.

Východiskovými surovinami sú bežné chemikálie, ako napr. 2-, 3- a 4- aminofenoly, 2,3-epoxy-l-propanol alebo látky opísané v literatúre. Sú to napr. alkoxyfenylizokyanáty a anilíny opísané v literatúre (Čižmárik J., Borovanský A., Švec P.: Acta Facult Pharm Univ Comeniane 29, 53 (1976)). Nasledujúce príklady bližšie osvetľujú, ale nijako neobmedzujú prípravu a vlastnosti zlúčenín podľa vynálezu.The starting materials are common chemicals such as e.g. 2-, 3- and 4-aminophenols, 2,3-epoxy-1-propanol, or substances described in the literature. They are eg. alkoxyphenylisocyanates and anilines described in the literature (Čižmárik J., Borovanský A., Svec P .: Acta Facult Pharm Univ Comeniane 29, 53 (1976)). The following examples illustrate but do not limit the preparation and properties of the compounds of the invention.
