Procedure

To [6-(6-cyclopropyl-pyridin-3-ylamino)-2-fluoro-pyridin-3-yl]-(4-methoxy-7-triisopropylsilanyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanol (73, 70 mg, 0.12 mmol) in 10.0 mL of 1,2-dichloroethane, triethylsilane (1.00 mL, 6.26 mmol) and trifluoroacetic acid (0.60 mL, 7.8 mmol) are added and the reaction stirred at 80° C. for 4 hours. The reaction is poured into 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 concentrated under vacuum to provide the desired compound (P-4004, 11.8 mg). MS (ESI) [M+H+]+=390.9.
