Versuchsvorschrift

To a vial containing 2,4-dichloro-5-fluoro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (389.5 mg, 1.2 mmol) was added m-nitrophenol (161 mg, 1.2 mmol), DMF (5 mL) and K2CO3 (320 mg, 2.3 mmol). The reaction mixture was heated at 60° C. for 1 hr. The reaction was diluted with EtOAc (120 mL) and water (30 mL). The organic layer was separated, washed with water (20 mL) and brine (20 mL), dried over Na2SO4 and evaporated to give an oil. The oil was purified via flash chromatography eluting with 100% heptanes. The solvent was removed to afford the title compound (505 mg, 99% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.34 (t, J=2.27 Hz, 1H) 8.22-8.28 (m, 1H) 7.90-7.96 (m, 1H) 7.86 (d, J=8.31 Hz, 1H) 7.78-7.84 (m, 1H) 5.59 (s, 2H) 3.54-3.66 (m, 2H) 0.84-0.99 (m, 2H) 0.00 (s, 9H). m/z (APCI+) for C18H20ClFN4O4Si 439.1 (M+H)+.
