Hydrazine → HCID 68539374, compound

Participants

Reaction Steps

Anhydrous hydrazine (94 mg, 2.96 mmol) was added to 2-[4-(4-amino-6,7,8,9-tetrahydro-1H-imidazo[4,5-c]quinolin-1-yl)butoxy]-1H-isoindole-1,3(2H)-dione (600 mg, 1.48 mmol) in ethanol (25 mL) at ambient temperature. The reaction was stirred overnight, and additional hydrazine (2 equivalents) was added. After stirring for 2 hours at ambient temperature, the reaction was concentrated under reduced pressure. The residue was diluted with dichloromethane and concentrated under reduced pressure three times to remove the hydrazine and then dried under vacuum to provide 550 mg of impure 1-[4-(aminooxy)butyl]-6,7,8,9-tetrahydro-1H-imidazo[4,5-c]quinolin-4-amine as an orange solid.
