実験手順

2-(1-Benzyl-1H-tetrazol-5-yl)-3-methoxyphenylamine (Intermediate 13, 0.115 g) was dissolved in pyridine (0.16 mL) and DCM (2 mL). Benzenesulfonyl chloride (0.08 g) was added and the mixture was stirred overnight. The reaction mixture was diluted with DCM and washed with 1N hydrochloric acid, dried with magnesium sulfate and filtered. The filtrate was evaporated to dryness and the residue was purified by flash chromatography on silica, eluting with a mixture of DCM and methanol. The fractions containing the desired product were combined and evaporated to give the title compound as a colorless solid (0.11 g).
