Procedure

A solution of 3-[5-(diethoxymethyl)-3-thienyl]-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propanenitrile (70 mg, 0.0001 mol) in THF (1 mL, 0.01 mol) was treated with 1 M HCl in water (400 μL). The reaction was stirred at room temperature. Water was added and the product was extracted with ethyl acetate. The combined extracts were washed with saturated sodium chloride, dried over magnesium sulfate, filtered and concentrated to give 3-(5-formyl-3-thienyl)-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propanenitrile as a semisolid residue (60 mg, 98%). 1H NMR (400 MHz, CDCl3): δ □9.96 (s, 1H), 8.89 (s, 1H), 8.44 (m, 2H), 7.46 (1H), 5.73 (s, 2H), 4.15 (m, 1H), 3.73-3.43 (m, 3H), 1.35 (m, 1H), 1.01 (m, 2H), 0.03 (s, 9H); MS (ES): 479 (M+1).
