Versuchsvorschrift

To {5-[hydroxy-(7-triisopropylsilanyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methyl]-6-methyl-pyridin-2-yl}-(6-methoxy-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (75, 0.317 g, 0.501 mmol) dissolved in 15.0 mL of 1,2-dichloroethane, triethylsilane (1.00 mL, 6.26 mmol) was added, followed by trifluoroacetic acid (0.482 mL, 6.26 mmol). The reaction was stirred at 70° C. overnight, then concentrated under vacuum and combined with 1 N aqueous potassium carbonate and extracted with ethyl acetate. The organic layer was washed with brine, then dried with sodium sulfate, filtered and the filtrate adsorbed onto silica. This was purified by silica gel column chromatography eluting with 50-100% ethyl acetate in hexanes. Appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound (P-0019, 57.5 mg). 1H NMR was consistent with the compound structure.
