Hydroxylamine hydrochloride (24.3 mg, 0.35 mmol), sodium bicarbonate (44 mg, 0.52 mmol), and water (0.52 mL) were combined in a vial and stirred for 15 minutes. This solution was added to a vial containing 4-(5-chloropyridin-3-yl)-2-((4aR,7aR)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl)-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (85.8 mg, 0.175 mmol) dissolved in ethanol (1.2 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)-2-((4aR,7aR)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl)-N′-hydroxy-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carboximidamide. MS ESI calc'd. for C27H34ClN7O2 [M+H]+ 524. found 524.
