Procedure

To (6-chloro-pyridin-3-yl)-{6-fluoro-5-[hydroxy-(4-methoxy-7-triisopropylsilanyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methyl]-pyridin-2-yl}-carbamic acid tert-butyl ester (72, 105 mg, 0.160 mmol) in 3.8 mL of toluene, [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) 1:1 complex with dichloromethane (13.0 mg, 0.016 mmol) is added under an atmosphere of nitrogen. The reaction is stirred for 5 minutes, then cyclopropylmagnesium bromide (17, 1.60 mL, 1.0 M in tetrahydrofuran, 1.60 mmol) is added slowly. The reaction is heated at 65° C. for 5 hours, then poured into water 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 (73, 70 mg). MS (ESI) [M+H+]+=563.6.
