A solution of 5-(methylthio)-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidin-4-yl)-1H-pyrazol-1-yl]pentanenitrile (0.35 g, 0.00079 mol) in THF (4 mL, 0.05 mol) and 3.0 M HCl (HCl) in water (4 mL) was heated to reflux overnight. The solvent was removed by rotary evaporation to give a pale orange oil. The oil was stirred in ethanol (3 mL, 0.05 mol) and 8.0 M ammonium hydroxide in water (1 mL) overnight. The reaction was concentrated and purified by prep LCMS (C18 column eluting with a gradient of ACN/H2O containing 0.15% NH4OH) to give 125 mg of a white foam. The white foam was triturated with MTBE (˜1.5 mL). The resulting solid was filtered, washed and dried to give 80 mg of the product (32% yield).
