実験手順

A solution of 1.7 g of the butyl benzhydrazide mentioned under (4) above in 20 ml of dichloromethane is mixed with a solution of 3.5 g of 3-(5-nitro-2-furyl)acrylaldehyde in 20 ml of dichloromethane, and the mixture is stirred at room temperature. The yellow-brown product (precipitated after a reaction time of 3 hours) is sucked off, the filtrate is concentrated, and the resulting solid material is likewise isolated. The two precipitates are recrystallized together from 200 ml of ethanol.
