실험 절차

A mixture of crude 4-methoxybenzyl azide (45.3 g; prepared as described below) and ethyl cyanoformate (33 g) in xylene (300 ml) was heated at reflux for 48 hours. The mixture was evaporated at below 40° C. and under reduced pressure to leave a residue of ethyl 1-(4-methoxybenzyl)-1H-tetrazole-5-carboxylate (69.36 g), m.p. 52° C.
