Participants

Reaction Steps

Methanesulfonyl chloride (114.5 mg) was added to a solution of 4-[2-(2-aminobenzyl)tetrazol-5-yl]phenyl pivalate (0.351 g), obtained in example 78, and pyridine (79 mg) in dichloromethane (2 ml) under ice cooling, and stirring was continued for 15 h. The mixture was washed with water, dried and evaporated to dryness. The residue was purified by column chromatography on silica gel with ethyl acetate-hexane (1/2) as an eluate. Recrystallization from ethyl acetate-hexane gave 300 mg (70%) of the title compound.
