To a suspension of 3-cyclopentylprop-2-ynenitrile (0.4 g, 0.003 mol) in ACN (10 mL) was added 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidine (0.53 g, 1.7 mmol) and DBU (0.33 mL, 2.2 mmol). This mixture was stirred at room temperature for 50 minutes. The reaction mixture was partitioned between ethyl acetate and dilute HCl. The aqueous portion was separated and extracted with ethyl acetate. The combined organic extracts were washed with dilute HCl and brine, were dried over sodium sulfate, filtered and concentrated in vacuo. The crude residue was purified by flash column chromatography (ethyl acetate/hexanes) to yield the desired product (540 mg, 74%).
