반응 단계
A mixture comprising 3.00 g (12.9 mmol) 6-bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (CAS-No: 784150-41-0), 90 mL tetrahydrofuran, 3.0 mL prop-2-yn-1-ol, 246 mg copper(I) iodide, 746 mg tetrakis(triphenylphosphine)palladium(0) and 3.93 mL N,N-diisopropylethylamine was heated at 80° C. for 4 hours. Water was added and the mixture extracted with ethylacetate/methanol (8:2). The organic layer was washed with brine and dried over sodium sulfate. After filtration and removal of the solvents the residue was purified by chromatography to give 833 mg (31%) of the title compound.
