実験手順

2-chloro-5-(trifluoromethyl)pyridine (0.181 g, 1.00 mmol) was added to a stirred suspension of 5-(3,4-bis-benzyloxy-5-nitro-phenyl)-2H-tetrazole (0.4 g, 1.00 mmol) and potassium carbonate (0.14 g, 1 mmol) in acetonitrile (10 mL). The reaction mixture was stirred at room temperature till completion, then diluted with dichloromethane and washed with water. The organic phase was separated, dried over anhydrous magnesium sulphate, filtered and evaporated to dryness to leave a crude residue that was recrystallised from a dichloro-methane/isopropanol mixture to afford 2-(5-(3,4-bis(benzyloxy)-5-nitrophenyl)-2H-tetrazol-2-yl)-5-(trifluoromethyl)pyridine, 0.389 g (71%).
