Reaction Steps

Tris(dimethylamino)sulfonium difluorotrimethylsilicate (239 mg) was added to a mixture of 4-[4-fluoro-3-(trifluoromethyl)phenyl]-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile (200 mg) and DMAc (3 mL), and the mixture was stirred at 100° C. for 1 hour under microwave irradiation. After the reaction mixture was cooled to room temperature, the reaction mixture was purified by silica gel column chromatography (Hex:EtOAc=98:2 to 60:40), whereby 4-[4-fluoro-3-(trifluoromethyl)phenyl]-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile (81 mg) was obtained as a pale yellow solid.
