Procedure
To a solution of 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidine (61.4 mg, 0.195 mmol) and 1-[(E)-2-cyanovinyl]cyclopropanecarbonitrile (23 mg, 0.19 mmol) in ACN (2 mL) was added DBU (58 μL, 0.39 mmol) and the resulting mixture was stirred for 16 hours. The ACN was evaporated, and the residue was dissolved in ethyl acetate. This solution was washed with 1.0 N HCl, water, and brine, and dried over sodium sulfate, and the solvent removed in vacuo. Flash column chromatography (eluting with a gradient from 0-80% ethyl acetate in hexanes) afforded the product (49 mg, 58%).
