실험 절차

2.74 g (54.75 mmol) of hydrazine hydrate are introduced into 10 ml of methanol, and a solution of 3.00 g (14.60 mmol) of 2-chlorobenzyl bromide in 5 ml of methanol is added at RT. The temperature rises to 35–40° C. during this, and the mixture is then stirred at RT for 3 hours. The solvent is removed in vacuo, and the residue is taken up in 100 ml of diethyl ether, dried over magnesium sulfate and filtered off.
