Reaction Steps

A solution of (2S)-1-[(1S,4S)-5-(1H-benzimidazol-2-ylcarbonyl)-2,5-diazabicyclo[2.2.1]hept-2-yl]-3,3-dimethyl-1-oxo-2-butanamine (120 mg, 0.34 mmol), 6-methyl-1H-indole-2-carboxylic acid (60 mg, 0.34 mmol), EDC (78 mg, 0.41 mmol), HOBt (9 mg, 0.068 mmol), NMM (103 mg, 1.02 mmol) in CH2Cl2 (2 mL) was stirred at room temperature for 18 h. The reaction was diluted with water and CH2Cl2 then washed with sat. NaHCO3 (20 mL) and brine (20 mL). The solution was dried over anhydrous Na2SO4 and concentrated to give the crude product, which was purified by reverse phase HPLC: 50-80% ACN/Water (0.1% TFA). Concentration of the fractions containing product afforded the title compound (105 mg) as a white solid. LCMS (m/z): 513.1 (M+H). 1H NMR (400 MHz, CDCl3) δ ppm: 0.90-1.10 (m, 9H), 1.75-2.20 (m, 2H), 2.30-2.40 (m, 3H), 3.45-3.95 (m, 3H), 4.00-5.25 m, 4H), 6.20-6.75 (m, 1H), 6.80-7.70 (m, 9H), 9.30-9.70 (m, 1H)
