PROCESS FOR PRODUCTION OF CARBOXYLIC ACID CHLORIDE COMPOUND |
摘要 |
The present invention discloses methods for producing a carboxylic acid chloride compound which comprises the step of reacting an alkyl-substituted cyclohexyl carboxylic acid with a chlorinating agent in the presence of a specific urea compound. According to this invention, it is possible to produce a carboxylic acid chloride compound which has high reaction speed, and whose product has high purity or high yield. Thus produced carboxylic acid chloride compound is useful as an intermediate for producing D-phenylalanine derivatives which are used as agents for treating diabetes.
