Abstract

Inventia se refera la un procedeu de preparare a esterului acidului D 2-izopropil-2-paraclorfenilacetic cu alcoolul (S) alfacian-3-fenoxibenzilic conform caruia esterul acidului D 2.izopropil-2-paraclorfenilacetic cu alcool (RS) alfa-cian-3-fenoxibenzilic este tratat cu un agent bazic, de exemplu amoniac, într-un solvent în care esterul alcoolului (S) este insolubil, de exemplu izopropanol.The invention relates to a process for the preparation of 2-isopropyl-2-para-chlorophenylacetic acid D-alpha-3-phenoxybenzyl alcohol (S) ester according to which the 2-isopropyl-2-chloro- phenylacetic acid ester of (RS) 3-phenoxybenzyl is treated with a basic agent, for example ammonia, in a solvent in which the ester of the alcohol (S) is insoluble, e.g. isopropanol.
