6-(Methylsulfonyl)-3-[(4-oxo-1-piperidinyl)methyl]-2-[3-(trifluoromethyl)phenyl]-N-[(1R)-2,2,2-trifluoro-1-phenylethyl]-4-quinolinecarboxamide (0.093 g, 0.140 mmol) was dissolved in dichloromethane (1.4 mL) and acetic acid (0.012 mL, 0.210 mmol). (S)-2-Methylpyrrolidine (0.036 g, 0.420 mmol) was added followed by sodium triacetoxyborohydride (59.4 mg, 0.280 mmol). The mixture was stirred at room temperature for 2 d. The solvent was removed under reduced pressure, and the residue was purified via HPLC (Waters, Sunfire 30×100 mm, 26-60% CH3CN/H2O with 0.1% TFA) to afford 3-({4-[(2R)-2-methyl-1-pyrrolidinyl]-1-piperidinyl}methyl)-6-(methylsulfonyl)-2-[3-(trifluoromethyl)phenyl]-N-[(1R)-2,2,2-trifluoro-1-phenylethyl]-4-quinolinecarboxamide (0.035 g, 32% yield). MS (m/z) 733.3 (M+H+).
