Reaction Steps

To a suspension of 5-(R)-(4-Chloro-phenyl)-3-(4-Iodo-benzyl)-oxazolidin-2-one (50 mg, 0.12 mmol), lead acetate (3 mg, 0.012 mmol), 2-(dicyclohexyl phosphino) biphenyl (5 mg, 0.014 mmol) and cesium carbonate (118 mg, 0.36 mmol) in toluene (2.5 mL), was added 2-pyridyl methyl piperazine and the reaction flask was heated at 100° C. for 3 h. The reaction mixture was diluted with dichloromethane (6 mL), washed with water (3 mL), brine (3 mL), dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by chromatography on silica gel, eluting with dichloromethane containing 0.5-2% ammonia (2 M) in methanol The title compound was isolated as an off white solid (30 mg, 54%). 1H NMR (300 MHz, CDCl3): δ 8.6 (m, 1H), 7.69 (m, 1H), 7.44 (d, 1H), 7.35 (m, 2H), 7.25 (m, 5H), 6.88 (m, 2H), 5.42 (t, 1H), 4.45 (d, 1H), 4.33 (d, 1H), 3.75 (m, 3H), 3.24 (m, 5H), 2.69 (m, 4H).
