Reaction Steps

A solution of N-{[(1,1-dimethylethyl)oxy]carbonyl}-3-methyl-L-valine (3 g, 13 mmol) (2-[(1S,4S)-2,5-diazabicyclo[2.2.1]hept-2-ylcarbonyl]-1H-benzimidazole (3 g, 12.4 mmol), EDC (2.8 g, 14.8 mmol), HOBt (334 mg, 2.5 mmol), NMM (3.7 g, 37.1 mmol) in CH2Cl2 (50 mL) was stirred at room temperature for 18 h. The reaction was diluted with water and CH2Cl2 then washed with sat. NaHCO3 (50 mL) and brine (50 mL). The solution was dried over anhydrous Na2SO4 and concentrated to give the title compound (5.6 g) as a pale yellow solid. LCMS (m/z): 456.3 (M+H).
