Abstract

A találmány tárgya eljárás N-(diklór-acetil)-1-őxa-4- -aza-spirő[4,5]dekán előállítására őldószeres közegben, mőnő-etanől-amin, ciklőhexanőn és diklór-acetil-klőrid 1:1:(1–1,2) mólaránybantörténő reagáltatásával savmegkötő szer jelenlétében őly m dőn, hőgyaz N- -(diklór-acetil)-1-őxa-4-aza-spirő[4,5]dekán előállítását egylépésben, a kiindűlási anyagők 20 řC alatti hőmérsékleten 7–14 pH-értéken történő reagáltatásával őldószerként telített alifás és/v gyciklőalifás szénhidrőgént alkalmazva végzik, majd a reakcióelegyből azN-(diklór-acetil)-1-őxa-4-aza-spirő[4,5]dekánt ismert módőn kinyerik. ŕThe present invention relates to a process for the preparation of N- (dichloroacetyl) -1-oxa-4-aza-spiro [4,5] decane in a brewing medium, from 1: 1 ethanolic amine, cyclohexane and dichloroacetyl chlorine. 1-1.2) reacting in molar ratio in the presence of an acid scavenger in the same manner, producing a thermoplastic N- (dichloroacetyl) -1-oxa-4-aza-spiro [4,5] decane in a single step at a temperature below 20 20C. Reaction at pH 7-14 is carried out using saturated aliphatic and / or cyclic aliphatic hydrocarbon as the cooling agent, and then the N- (dichloroacetyl) -1-oxa-4-aza-spiro [4,5] decane is recovered in a known manner. ŕ
