Participants

Reaction Steps

To [5-(7-benzenesulfonyl-4-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-ylmethyl)-pyridin-2-yl]-(6-trifluoromethyl-pyridin-3-ylmethyl)-amine (53, 0.010 g, 0.017 mmol) in 0.597 mL of tetrahydrofuran under nitrogen, tetra-n-butylammonium fluoride (0.0557 mL, 1.00 M in tetrahydrofuran, 0.0557 mmol) was added. The reaction was stirred for 3 hours, then quenched with water. The aqueous layer was separated and extracted with ethyl acetate. The organic layers were combined and washed with brine, dried over magnesium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography, eluting with 25% methanol in dichloromethane. Appropriate fractions were combined and solvents removed under vacuum to provide the desired compound (P-0104, 0.002 g). MS (ESI) [M+H+]+=453.1.
