Trifluoroacetic acid → 2,5-Difluoro-4-{[(1S*,2R*)-2-(1-methyl-1H-pyrazol-5-yl)cyclopentyl]oxy}-N-(pyrimidin-4-yl)benzenesulfonamide

Participants

Reaction Steps

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-(1-methyl-1H-pyrazol-5-yl)cyclopentyl]oxy}-N-(pyrimidin-4-yl)benzenesulfonamide (411 mg, 0.70 mmol) prepared in Example 31a, triethylsilane (0.20 mL), trifluoroacetic acid (2.0 mL) and dichloromethane (2.0 mL), to yield the title compound (241 mg, 79%) as a colorless solid.
