Reaction Steps
To a stirred solution of (S)-2-tert-butoxycarbonylamino-3-(3,4-dichloro-phenyl)-propionic acid (0.67 g, 2.00 mmol) in MeOH (13 mL) at 0° C. was added SOCl2 (0.29 mL, 4.00 mmol). The reaction mixture was allowed to stir and warm to rt overnight. The mixture was concentrated to provide the product as a white solid (0.56 g, 99%). 1H NMR (400 MHz, DMSO-d6): 8.66 (br s, 2H), 7.65-7.60 (m, 2H), 7.26 (dd, J=8.2, 1.9, 1H), 4.37 (br s, 1H), 3.72 (s, 3H), 3.18-3.14 (m, 2H).
