実験手順

To 2.59 g (0.01 mole) of 1-(4-chlorobenzyl)amino-1-methylthio-2-nitroethylene were added 45 ml of EtOH, 10 ml of THF and 1.02 g of 25% aqueous ammonia and the mixture was stirred at an external temperature of 60° C. for 5.5 hours. During this period, 1.02 g each of 25% aqueous ammonia was added after 1, 2 and 3 hours of reaction. The reaction mixture was ice-cooled and stirred, whereupon crystals separated out. The crystals were collected by filtration, washed with EtOH and ether in that order, and dried. The procedure gave 1.11 g of the title compound as white crystals.
