실험 절차
2-(1-methyl-1H-pyrazol-5-yl)-4-(trifluoromethoxy)phenol (Preparation 533, 50.0 mg, 0.20 mmol) and 3-cyano-4-fluoro-N-(1,3-thiazol-2-yl)benzenesulfonamide (Preparation 46, 57 mg, 0.20 mmol) were used to prepare the title compound using Method F above. The product was purified by flash column chromatography (SiO2) eluting with dichloromethane:ethyl acetate (gradient 8:2 to 2:8, by volume) to afford the title compound, 98 mg, 97% yield.
