Reaction Steps

A mixture of 2-fluoro-4-(3-fluoro-benzyloxy)-benzoic acid (400 mg, 1.5 mmol) and carbonyldiimidazole (258 mg, 1.6 mmol) in dry THF (5 mL) under Argon was heated under reflux for 30 min. After cooling to room temperature a suspension of H-alanine-NH2 HCl (226 mg, 1.8 mmol) containing triethylamine (184 mg, 1.8 mmol) in dry THF (1 mL) was added and the resulting mixture heated under reflux for 1 h. After cooling to room temperature water (5 mL) was added and the resulting precipitate was filtered off and washed successively with hexane and diethylether to afford the title compound (272 mg, 54%) as a white solid. MS: m/e=335.3 (M+H+).
