実験手順

To a solution of methyl [(2,3-difluorobenzoyl)amino]acetate (0.250 g, 1.1 mmol) in methanol (7 mL) were added lithium hydroxide (0.053 g, 2.2 mmol) and water (3 mL). The reaction mixture was allowed to stir overnight. The mixture was diluted with water (20 mL) and acidified with 1N HCl (5 mL). The product was partitioned into DCM/methanol (4:1). The organic layer was dried over sodium sulfate and the solvent removed to give [(2,3-difluorobenzoyl)amino]acetic acid which was used in the next step without purification.
