Participants

Reaction Steps

Ethyl 2-(1H-1,2,3,4-tetrazol-5-yl)acetate (5.0 g, 32.0 mmol) was dissolved in dimethylformamide (20 ml), added with potassium carbonate (5.75 g, 41.6 mmol). The mixture was further added dropwise with 4-methoxybenzyl chloride (5.21 ml, 38.4 mmol) under ice cooling and stirred at the same temperature for 1 hour and 30 minutes and at room temperature for 15 hours. The solvent was evaporated, and the residue was diluted with toluene, washed with water and saturated brine, and dried over anhydrous sodium sulfate. Then, the solvent was evaporated and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1, v/v) to obtain the title compound (3.78 g, 42.7%) as colorless oil.
