Procedure

Two grams of 5-phenyltetrazole (13.68 mM) were slowly added to 5 ml of a methanol solution containing 770 mg (13.68 mM) of potassium hydroxide at room temperature. Two milli liters of a methanol solution containing 1.48 g (13.68 mM)of methyl chloroacetate were dropwise added to the resultant solution at room temperature. After the completion of the addition, the reaction solution was refluxed for 20 hours and cooled. The reaction solution was diluted with ethyl acetate and washed with water. The organic phase was dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel chromatography (elute is chloroform), to give 0.54 g of methyl 5-phenyl-1-tetrazoleacetate (yield: 18.1%).
