Reaction Steps

The reaction and aftertreatment were conducted in the same manner as in Example 1a by using the N-(2,4-dimethoxybenzyl)-2,4,5-trifluoro-N-(pyrimidin-4-yl)benzenesulfonamide (200 mg, 0.455 mmol) prepared in Example 14b, (1S*,2R*)-2-(1-ethyl-1H-pyrazol-5-yl)cyclopentanol (78.0 mg, 0.432 mmol) prepared in Example 37a, sodium hydride (63%; 24.7 mg, 0.648 mmol) and DMF (2.0 mL), to yield the title compound (210 mg, 81%) as a colorless oil.
