Versuchsvorschrift

A solution of benzaldehyde (5.3 g) in methanol (25 ml) was added to a solution of 2-hydrazino-5-t-butyl-1,3,4-thiadiazole (8.5 g) in methanol (40 ml). The mixture was stirred for 30 minutes, poured into water (100 ml) and filtered. The solid was crystallised from ethanol to give benzaldehyde 5-t-butyl-1,3,4-thiadiazolyl hydrazone (8.2 g, 63%) as a white powder, mp 195°-196° C.
