実験手順

A mixture of (3-amino-4-fluorophenoxy)acetic acid methyl ester (0.39 g), 3-oxo-2-[4-(pyrrolidine-1-carbonyl)benzyl]pentanoic acid methyl ester (1.0 g), polyphosphoric acid (2 g) and dioxane (20 mL) was heated at 120° C. for 18 hours. The mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate. The combined extracts were dried over magnesium sulfate and the solvent removed under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with a mixture of dichloromethane and methanol (9:1 by volume) to afford title compound, 0.25 g.
