실험 절차
653 mg (3.33 mmol) of 4-nitrophenyl methylcarbamate and 473 mg (3.22 mmol) of N,N-diisopropylethylamine are added to 500 mg (3.33 mmol) of 4-methylbenzoic acid hydrazide in 15 ml dichloromethane and the mixture stirred overnight at room temperature. The precipitate formed is recovered by filtration, washed with diethyl ether and dried in vacuo. 602 mg (87% of theory) of the target compound are thus obtained.
