A solution of 6-[2-(4-methylsulfonyl-3-trifluoromethyl-phenyl)-3-(tetrahydro-pyran-2-yl)-propionylamino]-nicotinic acid methyl ester (prepared as in Example 15, 129 mg, 0.25 mmol) in ethyl ether (6 mL) cooled to 0° C. was treated with a 1.0M solution of lithium aluminum hydride solution in diethyl ether (0.30 mL, 0.30 mmol). The orange-colored reaction mixture was stirred at 0° C. for 1 h. The reaction was then quenched by the dropwise addition of water (10 mL) and extracted with ethyl acetate (2×10 mL). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated in vacuo. Biotage chromatography (FLASH 40S Silica, 8/2 hexanes/ethyl acetate) afforded N-(5-hydroxymethyl-pyridin-2-yl)-2-(4-methanesulfonyl-3-trifluoromethyl-phenyl)-3-(tetrahydro-pyran-2-yl)-propionamide (44 mg, 36%) as a cream foam: EI-HRMS m/e calcd for C22H25F3N2O5S (M+H)+ 487.1509, found 487.1514.
