Conditions

Temperature: 80 °C

Procedure

Potassium carbonate (2.2 g) was added to a solution of 4-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (3.7 g) obtained in Step 1 and 1-bromo-2-(tert-butyldimethylsilyloxy)-3-butene (3.5 g) obtained in Step 2 in DMF (26 ml) at room temperature, and the mixture was stirred at 80° C. for 5 hours. After cooling the reaction mixture, water and ethyl acetate were added thereto, and the generated insoluble matter was filtered off. The organic layer was separated, washed with water and a saturated sodium chloride solution, and dried over anhydrous sodium sulfate. The solvent was then distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography (developing solvent: hexane/ethyl acetate) to obtain the title compound as a light-yellow solid (2.25 g).
