実験手順

A mixture of 1,1-dimethylethyl (1S,4S)-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (18.3 g, 92.5 mmol), 1H-benzimidazole-2-carboxylic acid, (15.0 g, 92.5 mmol), EDC (21.3 g, 111 mmol), HOBt (2.5 g, 18.5 mmol), NMM (28 g, 277.5 mmol) in CH2Cl2 (250 mL) was stirred at room temperature for 18 h. The reaction was diluted with water and CH2Cl2 then washed with sat. NaHCO3 (200 mL) and brine (200 mL). The solution was dried over anhydrous Na2SO4 and concentrated to give a crude product which was purified by column chromatography on silica gel (petroleum ether/ethyl acetate: 2/1) to give the title compound (20 g) as a white solid. LCMS (m/z): 343.2 (M+H).
