Abstract

Inventia se refera la un procedeu pentru prepararea N-(1-ciclohexenilmetil-2- pirolidinilmetil-8-etilsulfonil-1,5-benzodioxepan-6-carboxamidei cu formula I (vezi formula în pag. 1 a descrierii), caracterizat prin aceea ca acidul 1,5-benzodioxepan-6-carboxilic se trateaza cu acid clorsulfonic la temperatura camerei, cu formarea acidului 8-etilsulfonil-1,5- benzodioxepan-6-carboxilic, care, prin tratare cu bicarbonat de sodiu si sulfit de sodiu, la 70...80 degree C, urmata de refluxare cu iodura de etil, în prezenta de etanol ca solvent si hidroxid de sodiu ca acid bazic, duce la formarea clorurii acidului 8-etilsulfonil-1,5-benzodioxepan-6- carboxilic, care se condenseaza cu 1-(1-ciclohexenilmetil)-2-aminometilpirolidina.The invention relates to a process for the preparation of N- (1-cyclohexenylmethyl-2-pyrrolidinylmethyl-8-ethylsulfonyl-1,5-benzodioxepane-6-carboxamide of the formula I (see formula on page 1 of the description) 1,5-benzodioxepan-6-carboxylic acid is treated with chlorosulfonic acid at room temperature to form 8-ethylsulfonyl-1,5-benzodioxepan-6-carboxylic acid, which, by treatment with sodium bicarbonate and sodium sulfite, at 70 DEG-80 DEG C., followed by refluxing with ethyl iodide, in the presence of ethanol as the solvent and sodium hydroxide as the base acid, leads to the formation of 8-ethylsulfonyl-1,5-benzodioxane-6-carboxylic acid chloride, which is condensed with 1- (1-cyclohexenylmethyl) -2-aminomethylpyrrolidine.
