Procedure
1-[2-(Trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine-4-carbonitrile (0.05 g, 0.0002 mol) was dissolved in ethanol (2.0 mL, 0.034 mol), and then hydroxylamine hydrochloride (0.023 g, 0.00033 mol) and potassium carbonate (0.10 g, 0.00073 mol) were added. The reaction was heated to reflux for 5 h, and the reaction was then allowed to cool to rt and filtered to remove the solids. The filtrate was concentrated to give the product 0.06 g as yellow oily residue, LC/MS (M+H)+ 307.
