실험 절차

Piperazine-1-carboxylic acid tert-butyl ester (17.43 g) and 2-phenylacrylic acid (18 g) in iso-propanol (500 ml) was heated at reflux for four days. The resulting precipitate was filtered, washed with diethyl ether and dried under vacuum to give the title compound as a white solid (17 g; MS: APCI+(M+H) 335).
