Procedure

To {6-fluoro-5-[hydroxy-(7-triisopropylsilanyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methyl]-pyridin-2-yl}-(4-methoxy-benzyl)-carbamic acid tert-butyl ester (67, 27 g, 42.5 mmol) in 700 mL of acetonitrile, triethylsilane (67.8 mL, 425 mmol) and trifluoroacetic acid (32.7 mL, 425 mmol) were added. The reaction was stirred at 50° C. overnight, solvents removed under vacuum, and the residue taken up in ethyl acetate and poured into aqueous potassium carbonate. The organic layer was separated, concentrated under vacuum and purified by silica gel column chromatography, eluting with 0-10% methanol in dichloromethane. Appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound (P-0105, 4.5 g, 12.38 mmol, 29.2% yield).
