Reaction Steps

A mixture of 1-(8-{2-[4-(1,3-benzodioxol-5-yl)piperidin-4-yl]ethyl}-8-azabicyclo[3.2.1]oct-3-yl)-2-methyl-1H-benzimidazole dihydrochloride (0.20 g, 0.39 mmol), triethylamine (0.17 mL, 1.25 mmol) and isobutyric acid (34 mg, 0.39 mmol) in dimethylformamide (1.25 mL) was treated with O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (163 mg, 0.43 mmol) and the resulting mixture was stirred for 1 h at rt. The mixture was diluted with water and the resulting precipitate was collected, washed with saturated sodium bicarbonate solution, with water and dried to give 1-((1R,5S)-8-{2-[4-(1,3-benzodioxol-5-yl)-1-isobutyrylpiperidin-4-yl]ethyl}-8-azabicyclo[3.2.1]oct-3-yl)-2-methyl-1H-benzimidazole as a solid (0.15 g, 72%).
