실험 절차

Phenyl N-cyano-4-{2-[3-(2-methyl-1H-benzimidazol-1-yl)-8-azabicyclo[3.2.1]oct-8-yl]ethyl}-4-phenylpiperidine-1-carboximidoate (100 mg, 0.175 mmol) and a solution of ammonia in methanol (2 mL, 1.4 M) was stirred at ambient temperature for 20 hours. After evaporation of the excess ammonia and the solvent, the residue was subject to flash chromatography (Mega Bond Elut Si, MeOH/EtOAc, 10% to 40%) to afford N′-cyano-4-{2-[3-(2-methyl-1H-benzimidazol-1-yl)-8-azabicyclo[3.2.1]oct-8-yl]ethyl}-4-phenylpiperidine-1-carboximidamide as amorphous solid (79 mg, 91%). 1H NMR (CDCl3, 300 MHz): δ 7.68-7.65 (m, 1H), 7.42-7.34 (m, 2H), 7.30-7.24 (m, 4H), 7.20-7.18 (m, 2H), 6.11 (s, 2H), 4.65 (t, J=8.5 Hz, 1H), 3.82-3.78 (m, 2H), 3.27-3.20 (m, 4H), 2.53 (s, 3H), 2.45-2.25 (m, 4H), 1.96-1.84 (m, 10H), 1.64 (d, J=7.5 Hz, 2H). HRMS m/z (M+H)+ calcd: 496.3189, obsd: 496.3181.
