Procedure
Hydroxylamine hydrochloride (37.7 mg, 0.54 mmol), sodium bicarbonate (68.4 mg, 0.81 mmol), and water (0.54 mL) were combined in a vial and stirred for 15 minutes. This solution was added to a vial containing 4-(5-chloropyridin-3-yl)-3-[(1R or S)-1-(trans-4-methylcyclohexyl)ethyl]-2-(prop-1-en-2-yl)-3H-imidazo[4,5-c]pyridine-6-carbonitrile (114 mg, 0.27 mmol) dissolved in ethanol (1.3 mL). The mixture was sealed and heated at 100° C. for 1 hour. The reaction was cooled to room temperature, quenched with water, and extracted with ethyl acetate (2×). The combined organic layers were dried over sodium sulfate, filtered, and concentrated to afford 4-(5-chloropyridin-3-yl)-N-hydroxy-3-[(1R or S)-1-(trans-4-methylcyclohexyl)ethyl]-2-(prop-1-en-2-yl)-3H-imidazo[4,5-c]pyridine-6-carboximidamide. MS ESI calc'd. for C24H29ClN6O [M+H]+ 453. found 453.
