실험 절차
A mixture of 2-bromo-1-(4-chloro-phenyl)-ethanone (90.71 mmoles) and hydrazine-carbothioic acid O-ethyl ester (90.71 mmoles) in acetonitrile (84 ml) is stirred at ambient temperature for 3 hours. The solid formed is filtered off, washed with acetonitrile and ethyl ether and then dried in vacuo to yield the title product, which is used directly in the next Step.
