To (1-benzenesulfonyl-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-(2-methylsulfanyl-pyrimidin-5-yl)-methanol (35, 4.70 g, 10.5 mmol) in 120.0 mL of acetonitrile, triethylsilane (22.0 mL, 138 mmol) and trifluoroacetic acid (11.0 mL, 143 mmol) are added. The reaction is stirred at 80° C. for 3 hours, then concentrated under vacuum, mixed with aqueous potassium carbonate and extracted with ethyl acetate. The organic layer is dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is purified by silica gel column chromatography eluting with 20-100% ethyl acetate in hexane. Appropriate fractions are combined and solvents removed under vacuum to provide the desired compound (36, 2.90 g).
