Procedure

To a solution of N-[5-chloro-2-(2-oxo-2,3-dihydro-benzooxazole-7-carbonyl) -pyridin-3-yl]-4-methyl-3-trifluoromethyl-benzenesulfonamide (41 mg) in THF (1 mL) and H2O (0.1 mL) was added NaBH4 (10 mg). The mixture was stirred at room temperature for 1 h, diluted by EtOAc (3 mL) and quenched by saturated aqueous NH4Cl solution (1 mL). The organic layer was separated, dried (Na2SO4), filtered and evaporated in vacuo. The residue was purified by flash chromatography (silica) to afford the title compound as a white powder. MS (M+H)+: 514.0.
