Reaction Steps

To a solution of 1H-tetrazole-5-amine (1.00 g, 11.8 mmol) and pyridine (1.15 ml, 14.1 mmol) in tetrahydrofuran (39 ml) was added 2,2,2-trichloroethyl chloroformate (1.95 ml, 14.1 mmol) with ice-cooling and the mixture was stirred at room temperature for 1 hour. Water was poured into the reaction mixture and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. To the residue was added hexane and a solid was collected by filtration to obtain the desired product (1.29 g, 42.1%).
