Procedure
To a solution of biphenyl-4-yl-(1-pyrimidin-2-yl-1,2,3,6-tetrahydro-pyridin-4-yl)-methanone (12.2 mg, 0.0355 mmol) in methanol (0.5 ml), was added CeCl3 heptahydate (13.2 mg, 0.0355 mmol) and sodium borohydride (1.5 mg, 0.0355 mmol) at room temperature. The mixture was stirred for 1 hour and diluted with EtOAc (10 ml). The mixture was washed with water (5 ml), brine (5 ml), dried (MgSO4), filtered, and concentrated under reduced pressure to furnish the crude product. This material was purified by column chromatography (6% MeOH/CH2Cl2) to give the title compound (12 mg, 98%) as a white gel: 1H NMR (CDCl3, 400 MHz) δ 8.36 (d, J=6.4 Hz, 2H), 7.62-7.37 (m, 9H), 6.46 (t, J=6.4 Hz, 1H), 6.02 (m, 1H), 5.24 (m, 1H), 4.31 (m, 2H), 3.96 (m, 1H), 3.83 (m, 1H), 2.14 (m, 2H); MS calc'd for C22H22N3O [M+H]+: 344; Found: 344.
