Reaction Steps

To a solution of tert-butyl 3-(4-(4-fluoro-2-(trifluoromethyl)phenyl)piperidine-1-carbonyl)-4,5-dihydro-1H-pyrazolo[3,4-c]pyridine-6(7H)-carboxylate (74 mg, 0.15 mmol) in CH2Cl2 (3 mL) and methanol (1 mL) was added 2 N HCl (2 mL, 2M in Et2O). The mixture stirred for 4 h at ambient temperature. The reaction mixture was diluted with Et20 (30 mL) and the resulting solids were collected by filtration to give (4-(4-fluoro-2-(trifluoromethyl)phenyl)piperidin-1-yl)(4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridin-3-yl)methanone hydrochloride as a white solid (64 mg, 98%): 1H NMR (300 MHz, DMSO-d6) δ 13.14 (s, 1H), 9.16 (br s, 2H), 7.73-7.68 (m, 1H), 7.59-7.50 (m, 2H), 4.84-4.69 (m, 1H), 4.32-4.25 (m, 2H), 3.26-3.03 (m, 2H), 2.89-2.81 (m, 2H), 2.68-2.48 (m, 4H), 1.73 (m, 4H); ESI MS m/z 397 [M+H]+.
