Reaction Steps
To a solution of 1,4-dibromobenzene (213.3 mg, 0.904 mmol) in THF (4 ml), was added n-BuLi (2.5 M in hexanes, 0.362 ml, 0.904 mmol) at −78° C. After being stirred for 30 minutes at the same temperature, a solution of 1-pyrimidin-2-yl-piperidin-4-one (80 mg, 0.452 mmol) in THF (3 ml) was added. The mixture was allowed to warm to room temperature and stirred for 1 hour. The reaction was quenched with addition of water (10 ml) and EtOAc (50 ml). The organic layer was washed with brine (5 ml), dried (MgSO4), filtered, and concentrated under reduced pressure to furnish the crude product. This material was purified by column chromatography (40% EtOAc/hexanes) to give 4-(4-Bromo-phenyl)-1-pyrimidin-2-yl-piperidin-4-ol as a colorless oil (140 mg, 93%): 1H NMR (CDCl3, 400 MHz) δ 8.33 (d, J=6.4 Hz, 2H), 7.47 (d, J=12.0 Hz, 2H), 7.41 (d, J=12.0 Hz, 2H), 6.49 (t, J=6.4 Hz, 1H), 4.72 (m, 2H), 3.40 (m, 2H), 2.05 (m, 2H), 1.78 (m, 2H); MS calc'd for C15H17BrN3O [M+H]+: 335; Found: 335.
