실험 절차

Sodium hydride and 1-benzylazepane-3-one were added to a THF solution of ethyl diethoxyphosphorylacetate under ice cooling and stirred for two hours at room temperature to give a stereoisomeric mixture of ethyl(1-benzylazepane-3-ylidene)acetate. After the obtained stereoisomeric mixture of ethyl(1-benzylazepane-3-ylidene)acetate was processed with 4M HCl-EtOAc solution, EtOH and 10% palladium carbon were added and stirred for 15 hours at room temperature under the hydrogen atmosphere to give ethyl azepane-3-ylacetate hydrochloride.
