실험 절차

To a solution of methyl 2-fluoro-5-(hexylamino)benzoate (185 mg; 0.73 mmol) in THF (15 mL) were added 4-[(4-butylphenyl)ethynyl]benzoyl chloride (260 mg; 0.88 mmol), DIEA (0.15 mL; 0.88 mmol) and DMAP (20 mg). The mixture was stirred at 60° C. under N2 atmosphere for 1 hour. It was then diluted with DCM (100 mL), washed with HCl 0.1N (50 mL) and a saturated solution of NaHCO3 (100 mL). The organic layer was dried over magnesium sulfate, filtrated and the solvent was removed under reduced pressure to give 480 mg of a brown solid. Purification by flash chromatography on silicagel (c-Hex/EtOAc, 90:10) gave 170 mg (45.3%) of the title compound as a white solid. HPLC, Rt: 6.14 min (purity=99.5%). LC/MS: M+(ESI): 514.3.
