Procedure

A mixture of 100 mg of methyl 5phenyl-1-tetrazoleacetate, 0.6 ml of acetic acid and 1 ml of a 4N-hydrochloric acid was stirred at 80° to 90° C. for 2 hours. The reaction solution was evaporated under reduced pressure. The precipitated solid was filtered, washed with cold water and recrystallized from 50% ethanol-water, to give 64.1 mg (yield: 69.2%) of 5-phenyhetrazole-lacetic acid.
