Participants

Reaction Steps

The reaction and aftertreatment were conducted in the same manner as in Example 1b by using the N-(2,4-dimethoxybenzyl)-3-fluoro-4-{[(1S*,2R*)-2-(1-methyl-1H-pyrazol-5-yl)cyclopentyl]oxy}benzenesulfonamide (0.92 g, 1.88 mmol) prepared in Example 16b, triethylsilane (1.5 mL), trifluoroacetic acid (15 mL) and dichloromethane (15 mL), to yield the title compound (0.60 g, 94%) as a colorless solid.
