to a suspension of DL-serine HCl (2.0 g, 12.8 mmol) in dichloromethane (10 mL) at 0° C. were added dropwise triethylamine (3.58 mL, 25.7 mmol) and (4-methoxyphenyl)-acetyl chloride (1.96 mL, 12.8 mmol). The mixture was stirred at 25° C. for 12 hours. The reaction mixture was washed with a saturated aqueous sodium chloride solution, separated, and evaporated to dryness and purified by column chromatography (hexanes: ethyl acetate from 25 to 100%). 3-Hydroxy-2-[2-(4-methoxy-phenyl)-acetylamino]-propionic acid methyl ester was isolated as a white solid (2g, 58%). ESI-MS m/z calc. 267.3, found 268.2 (M+1)+. Retention time of 1.83 minutes. 1H NMR (400 MHz, CDCl3) δ3.64 (s, 2H), 3.78 (s, 3H), 3.83 (s, 3H), 3.93 (qd, J=14.6 and 4.0 Hz, 2H), 4.66 (m, 1H), 6.40 (m, 1H), 7.01 (d, J=8.7 Hz, 2H), 7.23 (d, J=8.7 Hz, 2H).
