실험 절차

To a nitrogen gas purged mixture of 4-chloro-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (200 mg, 0.488 mmol), and (2-methoxyphenyl)boronic acid (96 mg, 0.64 mmol) in 2 M aqueous sodium carbonate (0.610 mL, 1.22 mmol) and DME (3.0 mL) was added tetrakis(triphenylphosphine)palladium(0) (56 mg, 0.049 mmol). The reaction was sealed and heated at 130° C. for 30 minutes. The reaction was then diluted with EtOAc and passed through a column of Celite and sodium sulfate to remove water and solids. The reaction solution was concentrated under reduced pressure and the crude product purified by silica chromatography eluting with 1-20% ethyl acetatehexane to afford 4-chloro-5-(2-methoxyphenyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine as a solid. LRMS (ESI) calcd for C19H25ClN3O2Si [M+H]+: 390, found 390.
