実験手順

To a mixture of 4-(phenylmethyl)-2-morpholinecarboxylic acid (1.61 g, 7.28 mmol) and DMF (0.1 mL) in CH2Cl2 (70 mL) was added oxalyl chloride (0.956 mL, 10.92 mmol) at 25° C. The mixture was stirred at this temperature for 1 hour and the mixture turned clear. The solvent and excess of oxalyl chloride were removed in vacuo, and the resulting residue was dissolved in CH2Cl2 (70 mL). 2-Amino-1-(4-chlorophenyl)ethanone (1.5 g, 7.28 mmol) and triethylamine (4.06 mL, 29.1 mmol) were added, and the resulting mixture was stirred overnight. Water (80 mL) was added to quench the reaction. The organic layer was separated and the aqueous layer was extracted with CH2Cl2 (2×80 mL). The combined organics were washed with sat. NaHCO3 aq. (80 mL), then brine (2×80 mL), dried (MgSO4), and evaporated to get 3.4 g yellow residue, which was chromatographed (EtOAc-petroleum ether, 1:1) to afford the title compound (2.5 g). LC-MS (ES) m/z=373 [M+H]+.
