実験手順

To a solution of 2,4-dichloro-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine (1470 mg, 4.62 mmol) in acetonitrile (10 mL) was added tert-butyl (3-hydroxyphenyl)carbamate (966 mg, 4.62 mmol) and K2CO3 (1280 mg, 9.24 mmol) and the mixture heated at 80° C. with stirring overnight. The reaction was then cooled to rt, EtOAc (20 mL) added, washed with water (50 mL), the aqueous layer extracted with EtOAc (three×20 mL), dried with MgSO4, filtered and stripped to a light oil. Upon standing, the light oil solidified to give the title compound (2052 mg, 90% yield) as a tan solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 9.38-9.83 (m, 1H) 7.73 (d, J=3.78 Hz, 1H) 7.41-7.46 (m, 2H) 7.51 (s, 1H) 6.97 (dt, J=5.98, 2.68 Hz, 1H) 6.58 (d, J=3.78 Hz, 1H) 5.64 (s, 2H) 3.54-3.67 (m, 2H) 1.54 (s, 9H) 0.91-0.96 (m, 2H) 0.00 (s, 9H). LCMS (ESI, pos): m/z (ESI+) for C23H31ClN4O4Si 491.20 (M+H)+.
