Procedure

{5-[(7-Benzenesulfonyl-4-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-hydroxy-methyl]-pyridin-2-yl}-(6-trifluoromethyl-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (52, 0.014 g, 0.020 mmol), trifluoroacetic acid (0.028 mL, 0.37 mmol), triethylsilane (0.071 mL, 0.45 mmol), and 0.21 mL of acetonitrile were combined in a round bottom flask. The reaction mixture was heated at reflux for 3 hours, then poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium 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 the solvents removed under vacuum to provide the desired compound.
