Benzoyl chloride → N-(5-Methyl-1,3,4-thiadiazol-2-yl)-N-(propan-2-yl)benzamide

Participants

Reaction Steps

N-(5-methyl-1,3,4-thiadiazol-2-yl)-1-methylethylamine (5 g, 0.032 mole) in pyridine (100 ml) was treated with benzoyl chloride (4.1 ml). The reaction mixture was stirred and heated to reflux for 51/2 hours. The pyridine was removed under reduced pressure and the residue treated with water and extracted with ether (× 3). The ethereal solution was dried, filtered and evaporated to dryness and the residue recrystallised from ether/petrol ether (40°-60° C.) to give the title compound as a pale yellow crystalline solid m.p. 82.5°-83.5° C.
