ABSTRACT:
The present invention relates to a novel process for preparing 1-aminocyclopropanecarboxylic acid hydrochloride (ACC.multidot.HCl) of the formula ##STR1## ACC.multidot.HCl is prepared from a cyclopropane-1,1-dicarboxylic acid diester via an 1-aminocarbonylcyclopropanecarboxylic acid ester intermediate and an alkali metal salt or alkaline earth metal salt of 1-aminocarbonylcyclopropanecarboxylic acid. The process represents a simplification and gives improved product yields.
