Procedure

6.905 g of tetrazole (100 mmol) and 1.75 ml of diisopropylethylamine (10 mmol) and 11.73 ml of epichlorohydrine (150 mmol) in anhydrous acetonitrile (30 ml) was stirred at 60° C. for 4 hours. The obtained solution was evaporated, dried on highvac and purified on a column of silica in chloroform-methanol 100:8. The first fraction provided pure 3-(2-H-tetrazol-2-yl)-2-hydroxy-1-chloropropane, 6.215 g (colorless oil, 38% Y), the second fraction yielded 9.208 g of pure 3-(1-H-tetrazol-1-yl)]-2-hydroxyl-1-chloropropane (sticky gum; 57% Y).
