Procedure
To an ice-cooled solution of 494 mg (0.852 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-[6-(3-oxo-morpholin-4-yl)-4-o-tolyl-pyridin-3-yl]-isobutyramide in 5 ml methanol and 5 ml tetrahydrofuran were added 635 mg (1.70 mmol) cerium(III)chloride heptahydrate. After stirring for 5 min, 64 mg (1.70 mmol) sodium borohydride were added in two portions within 2 min. After stirring for 3 h at 0° C., 1 ml acetone was added and stirring was continued for 10 min. The solvent was removed, the residue was re-dissolved in ethyl acetate and the organic phase was washed with saturated sodium carbonate solution, dried (magnesium sulfate) and evaporated. The crude material was purified by flash-chromatography to give 87 mg (16%) of the title compound as white crystals.
