実験手順
A solution of 85 mg (0.25 mmol) of 1-(t-butoxycarbonyl)-4-((2-benzyl)tetrazol-5-yl)piperidine (from Step C) in 2 mL of 1:1 v/v CH2Cl2/TFA was stirred at rt for 2 h. The solution was concentrated. Flash chromatography on silica gel using 19:1:0.1 v/v/v CH2Cl2/MeOH/NH4OH as the eluant afforded 57 mg (94%) of the title compound.
