実験手順

A mixture of 4-(4-fluoro-benzyloxy)-phthalic acid (185 mg, 0.64 mmol) and carbonyldiimidazole (109 mg, 0.67 mmol) in N,N-dimethylacetamide (3 mL) was stirred at room temperature for 10 min and then heated at 50° C. for 15 min. To this mixture was added N-acetylethylenediamine (78 mg, 0.76 mmol) and the resulting mixture heated under reflux for 20 min. After cooling to room temperature, the mixture was evaporated and the residue was purified by chromatography (SiO2, CH2Cl2:2N NH3/MeOH 98:2 to 9:1) to afford the title compound (139 mg, 62%) as an off-white solid. MS: m/e=357.3. (M+H+).
