Procedure

The reaction and aftertreatment were conducted in the same manner as in Example 1b by using the N-(2,4-dimethoxybenzyl)-2,5-difluoro-4-{[(1S*,2R*)-2-(pyridazin-4-yl)cyclohexyl]oxy}-N-(pyrimidin-4-yl)benzenesulfonamide (0.04 g, 0.07 mmol) prepared in Example 53c, triethylsilane (0.06 mL), trifluoroacetic acid (0.07 mL) and dichloromethane (0.74 mL), to yield the title compound (30 mg, 94%) as a colorless solid.
