反応手順
To DMTMM (76.1 g, 0.276 mol) and N-methylmorpholine (NMM; 32.9 mL, 0.300 mol) was added to a 0° C. solution of 2-morpholinoacetic acid (20.0 g, 0.138 mmol) and L-alanine benzyl ester hydrochloride (35.7 g, 0.166 mol) in DMF (100 mL) and DCM (200 mL). The reaction mixture was stirred for 4 h at ambient temperature then concentrated. EtOAc (500 mL) and water (500 mL) was added to the residue. The resulting two layers were separated and the aqueous phase was extracted with EtOAc (3×300 mL). The combined organic layers were washed with brine (3×500 mL), dried over anhydrous sodium sulfate, and concentrated. The residue was purified by flash column chromatography on silica gel (DCM/MeOH=100:3) to afford (S)-benzyl 2-(2-morpholinoacetamido)propanoate (21.1 g, 50% yield).
