Procedure

A mixture of 2-methyl-1-{8-[2-(4-phenyl piperidin-4-yl)ethyl]-8-azabicyclo[3.2.1]oct-3-yl}-1H-benzimidazole dihydrochloride (75 mg, 0.16 mmol), tetrahydro-3-furoic acid (18 mg, 0.16 mmol) and triethylamine (48 mg, 0.48 mmol) in dimethylformamide (0.5 mL) was treated with O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (68 mg, 0.18 mmol) and the resulting mixture was stirred at rt for 1 h. The reaction mixture was diluted with water and extracted with dichloromethane. The residue from the dichloromethane layer was purified by chromatography on silica gel eluting with 1:20 methanol:dichloromethane to give 2-methyl-1-((1R,5S)-8-{2-[4-phenyl-1-(tetrahydrofuran-3-ylcarbonyl)piperidin-4-yl]ethyl}-8-azabicyclo[3.2.1]oct-3-yl)-1H-benzimidazole as a clear oil (0.019 g, 23%). 1H NMR (400 MHz, DMSO-d6) δ 7.46 (m, 1H), 7.36 (m, 5H), 7.21 (m, 1H), 7.09 (m, 2H), 4.49 (m, 1H), 3.58-3.87 (m, 7H), 3.12-3.35 (m, 6H), 2.28-2.39 (m, 2H), 1.89-2.12 (m, 5H), 1.58-1.86 (m, 10H), 1.53-1.60 (m, 2H).
