A solution of the 4-({(1S,2R)-5,5-difluoro-2-[1-(4-methoxybenzyl)-1H-pyrazol-4-yl]cyclohexyl}oxy)-N-(2,4-dimethoxybenzyl)-2-fluoro-5-methyl-N-(pyrimidin-4-yl)benzenesulfonamide (0.15 g, 0.20 mmol) prepared in Example 143f, triethylsilane (0.16 mL) and trifluoroacetic acid (0.20 mL) in dichloromethane (2.0 mL) was stirred at 140° C. for 1 hour under microwave irradiation. The reaction solution was concentrated, and the residue was purified with silica gel chromatography (ethyl acetate) to yield the title compound (90 mg, 94%) as a colorless solid.
