실험 절차

A mixture of N-[2-(1-benzyl-1H-tetrazol-5-yl)-3-methoxyphenyl]-benzenesulfonamide (Intermediate 12, 0.104 g), ammonium formate (0.45 g) and palladium hydroxide (0.01 g) in ethanol (10 mL) was heated at reflux for 72 hours. The reaction mixture was filtered through celite and the filtrate was evaporated under vacuum. 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 (0.05 g).
