Reaction Steps

3-(Cyanomethylene)cyclobutanecarbonitrile (120 mg, 0.0010 mol) was combined with 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidine (0.1 g, 0.0003 mol) in acetonitrile (2 mL, 0.04 mol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (6 μL, 0.00004 mol) under nitrogen. The mixture was stirred at room temperature over the weekend. After evaporation to dryness, the crude mixture was purified by flash column, eluting with 0 to 10% MeOH in dichloromethane, to give the desired product. LCMS (M+H) 434.4.
