실험 절차

To a suspension of N-(3-fluoro-4-hydroxyphenyl)-1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (2.2 g, 6.4 mmol) and 4-chloropicolinamide (1 g, 6.39 mmol) in DMSO (12 mL) was added NaH (615 mg, 12.3 mmol, 50% dispersed in mineral oil). The reaction was stirred at 160° C. for 20 hours, then cooled to rt, and diluted with H2O (70 mL). The mixture was extracted with EtOAc (100 mL×3). The combined organic phases were washed with brine (100 mL), dried over Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (v/v)=1/4) to give the title compound as a white solid (0.85 g, 29%).
