Reaction Conditions

Reaction Steps

570 g (5 moles) of 2,5-dimethyl-1,3,4-thiadiazole and 275 g (2.5 moles) of salicylaldehyde are mixed and the mixture is slowly heated to 150° C. whilst passing nitrogen through it. The mixture is kept at 150° C. for 30 hours and is then cooled, the excess 2,5-dimethyl-1,3,4-thiadiazole is distilled off and the residue is recrystallized from methylglycol. 304 g (56% of theory) of yellow crystals of melting point 253°-254° are obtained.
