Versuchsvorschrift

To (1-benzenesulfonyl-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-(2-methylsulfanyl-pyrimidin-5-yl)-methanol (130, 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) were added. The reaction was stirred at 80° C. for 3 hours, then concentrated under vacuum and mixed with aqueous potassium carbonate and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with 20-100% ethyl acetate in hexane. Appropriate fractions were combined and solvents removed under vacuum to provide the desired compound (131, 2.90 g).
