Novel 1H-tetrazole-1-acetate esters and acids are prepared by reacting azidoacetate esters and acids with certain acyl cyanides or cyanoformates. The products of the process are useful as intermediates in the preparation of 1H-tetrazole-1-acetic acids which have utility in preparing certain cephalosporin and penicillin antibiotics.
