Procedure

In 10 ml of acetone was dissolved 0.40 g (3.1 mmol) of 4-methyl-1,2,3-thiadiazol-5-ylmethanol. After adding 1.6 g (12 mmol) of potassium carbonate and 0.80 g (4.5 mmol) of benzyl bromide, the resulting mixture was stirred for 10 hours with heating under reflux. After the reaction was completed, the insoluble matter was filtered off, the solvent was distilled off from the filtrate under reduced pressure, and the residue was purified by silica gel column chromatography using 3:1 mixture of n-hexane and ethyl acetate. Thus, 0.65 g of the objective compound was obtained.
