実験手順
To a solution of (3S)-5-oxo-4-(phenylmethyl)-3-morpholinecarboxylic acid (1.5 g, 6.4 mmol) (J. Chem. Soc., Perkin Trans. 1, 1985, 2577-2580) in THF (50 mL) was added dimethylamine (3.8 mL, 7.6 mmol, 2M in THF), EDC (1.46 g, 7.7 mmol), HOAt (1.06 g, 7.7 mmol) and NMM (3.5 mL, 30 mmol). The reaction mixture was stirred overnight and the THF was evaporated, replacing it with EtOAc. 1 M HCl was added and the phases were separated. The aqueous layer was extracted twice with EtOAc and the combined organics were dried over sodium sulfate. Concentration in vacuo yielded (3S)—N,N-dimethyl-5-oxo-4-(phenylmethyl)-3 morpholinecarboxamide, which was purified by RP-HPLC. LCMS: (M+H)+: 263.1.
