Nitrobenzoyl-3-cyclopropylaminoacrylates and a process for the preparation thereof

摘要

Nitrobenzoyl-3-cyclopropylaminoacrylates are prepared by two stage reaction: (a) The first stage is the synthesis of nitrobenzoyl-3-alkoxyacrylates from nitrobenzoylester compound and alkylorthoformate in organic acid solvent. (b) The second stage is the synthesis of nitrobenzoyl-3-cyclo propylamino acrylate from nitrobenzoyl-3-alkoxyacrylates and cyclopropylamine.
