Procedure

A solution of 2.40 g N-(bromomethyl)phthalimide (0.010 mol) and 2.00 g 1-phenyl-1H-tetrazole-5-thiol, sodium salt (0.010 mol) in 20 ml N,N-dimethylacetamide was stirred 0.5 hours. The slurry was then poured into water extracted with ethyl acetate, dried and concentrated in vacuo. The solid obtained was recrystallized from ethyl acetate/hexane to give 2.43 g (72.0%) of a colorless solid, m.p. 146°-7° C.
