Acetic Acid → HCID 86612245, compound

Participants

Reaction Steps

Sodium cyanoborohydride (0.54 g, 8.64 mmol, 3 eq) and acetic acid (7 mL) were added to a solution of 4-(4-amino-2-propyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)butyraldehyde O-methyloxime (0.94 g, 2.88 mmol, 1 eq) in methanol (7 mL) and stirred at ambient temperature for 20 minutes. The reaction mixture was concentrated under reduced pressure and diluted with dichloromethane (60 mL) and saturated aqueous sodium bicarbonate (40 mL). The phases were separated and the aqueous phase was adjusted to pH ˜8 with solid sodium bicarbonate and extracted with dichloromethane (2×20 mL). The combined organics were dried over magnesium sulfate, filtered, and then concentrated under reduced pressure to provide 1.01 g of 1-[4-(methoxyamino)butyl]-2-propyl-1H-imidazo[4,5-c]-1,5-naphthyridin-4-amine as a yellow solid.
