Reaction Steps

Benzyl (2R) 2-dibenzylamino-3-difluoromethoxy-propionate (3.1 g, 6.28 mmol) was stirred with Pd(OH)2 in methanol under H2 overnight. The reaction mixture was filtered and the filtrate concentrated to dryness, then triturated with diethyl ether to give (2R)-2-amino-3-(difluoromethoxy)propanoic acid (773 mg, 68.4%) as a white solid. 1H NMR (300 MHz, MeOD): δ(ppm) 6.49 (wt, 1H), 4.33 (dd, 1H), 4.22 (dd, 1H), and 3.88 (dd, 1H).
