Reaction Steps

To a solution of 3-hydroxy-5-[(1S)-2-methoxy-(1-methylethyl)oxy]-N-(1-methyl-1H-pyrazol-3-yl)benzamide (152 mg, 0.50 mmol) in acetonitrile (3.5 mL) was added potassium carbonate (345 mg, 2.5 mmol) and 3-chloro-4-fluoro-N,N-dimethylbenzenesulfonamide (237 mg, 1.0 mmol) and the mixture was heated under microwave conditions at 160° C. for 2 hours. The mixtures were filtered and evaporated. The residue was purified by flash chromatography (eluting with an increasing gradient of 60 to 100% ethyl acetate in isohexane) to afford the title compound (1.8 g, 98%).
