O-(propan-2-yl)hydroxylamine hydrochloride → 1-isopropoxy-2-methyl-1H-imidazo[4,5-c]quinoline

Participants

Reaction Steps

O-isopropylhydroxylamine hydrochloride (2.14 g, 1.7 eq) was added to a solution of N-(4-chloroquinolin-3-yl)acetamide (2.51 g, 1.0 eq) in ethanol (75 mL). The reaction mixture was heated at reflux for 2 hours and then concentrated under reduced pressure. The residue was partitioned between dichloromethane and aqueous saturated sodium bicarbonate. The organic layer was separated and concentrated under reduced pressure to provide 2.60 g of 1-isopropoxy-2-methyl-1H-imidazo[4,5-c]quinoline.
