Participants

Reaction Steps

A solution of 2-bromo-1,3,4-thiadiazole (3.14 g.) and aminoacetaldehyde diethyl acetal (5.1 g.) in benzene (75 ml) was refluxed for 20 hours. After cooling, the insoluble material was filtered off. The filtrate was concentrated under reduced pressure to give oil (6.3 g.). The oil was purified by column chromatography on silica gel (120 g.) using benzene and then ethyl acetate as developing solvent to give (1,3,4-thiadiazol-2-yl)aminoacetaldehyde diethyl acetal (3.3 g.), mp 108° to 112° C.
