Reaction Steps

The reaction and aftertreatment were conducted in the same manner as in Example 1b by using the 5-chloro-4-{[(1S*,2R*)-4,4-difluoro-2-(1-methyl-1H-pyrazol-5-yl)cyclohexyl]oxy}-N-(2,4-dimethoxybenzyl)-2-fluoro-N-(pyrimidin-4-yl)benzenesulfonamide (104 mg, 0.16 mmol) prepared in Example 131a, triethylsilane (0.10 mL), trifluoroacetic acid (1.0 mL) and dichloromethane (1.0 mL), to yield the title compound (72.2 mg, 90%) as a colorless solid.
