| titleOfInvention | Process for the preparation of ethyl-4-(trichloro-acetamido)-5-hexenoate |
| abstract | The present invention relates to a novel process for the preparation of ethyl 4- (trichloroacetamino) -5-hexenoate. According to the present invention, (i) dehydrated and formylated in the presence of erythritol formic acid during a thermal reaction; (ii) reacting the resulting 4- (formyloxy) -3-hydroxy-1-butene with triethyl orthoacetate under thermal reaction conditions to give ethyl 6- (formyloxy) -4-hexenoate in the presence of ethanol and hydrochloric acid. Converted to 6-hydroxy-4-hexanoate; (iii) converting the thus obtained ethyl 6-hydroxy-4-hexenoate by reaction with trichloroacetonitrile to ethyl 6- (trichloroacetimidyloxy) -4-hexenoate and then rearranging this compound thermally.
