Procedure

To a solution of 3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]pentanal (60 mg, 0.0002 mol) from Example 498, Step 2 in methanol (2 mL, 0.05 mol) was added hydroxylamine hydrochloride (16 mg, 0.00022 mol) and potassium bicarbonate (22 mg, 0.00022 mol). The reaction was stirred at room temperature for 2 h, 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 (1E)-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]pentanal oxime as a semisolid residue (50 mg, 80%). LC/MS (M+H)+: m/z=415.
