反応手順
1-iodobenzene (28.12 g, 137.84 mmol) was added to morpholine (12.0 g, 137.93 mmol). L-Proline (3.12 g, 27.13 mmol) was then added, followed by the addition of CuI (2.6 g, 13.68 mmol) and DMSO (120 mL). The resulting solution was stirred at 90° C. for 4 hours, and then the reaction mixture was then quenched by the addition of 300 mL of iced water. The resulting solution was extracted using dichloromethane (2×200 mL), and the organic layers combined, dried (Na2SO4) and concentrated. The residue was purified by column chromatography using a petroleum ether solvent system. The collected fractions were combined and concentrated to give 10 g (42%) of 4-phenylmorpholine as a white solid.
