Reaction Steps
LiOH (1.32 g, 31.5 mmol) was added to a stirred solution of (4-benzyloxy-benzoylamino)-acetic acid ethyl ester (2.47 g, 7.8 mmol) in THF:MeOH:H2O (2:2:1, 50 mL). The resulting mixture was stirred at room temperature overnight. The MeOH and THF were evaporated and the residue was diluted with water (20 mL) and acidified with 10% HCl solution. The resulting precipitate was washed with water followed by hexane and dried to afford 2.03 g (90.6 yield) of (4-benzyloxy-benzoylamino)-acetic acid. 1H NMR: (DMSO) δ 7.9 (d, 2H), 7.8 (s, 1H), 7.5 (m, 5H), 7.1 (d, 2H), 5.2 (s, 2H), 3.6 (d, 2H).
