Ammonium Hydroxide → HCID 67157055, compound

Participants

Reaction Steps

MCPBA (4.39 g of 77% purity, 25 mmol) was added to a solution of 3-bromo-12-methyl-11,12-dihydro-8H,10H-[1,4]oxazepino[4′,3′:1,2]imidazo[4,5-c]quinoline (2.6 g, 7.8 mmol) in chloroform (20 mL), and the reaction mixture was stirred overnight at room temperature. Aqueous ammonium hydroxide was added. The aqueous layer was separated and extracted twice with chloroform. The combined organic fractions were concentrated under reduced pressure and further dried under high vacuum to provide 3-bromo-12-methyl-5-oxido-11,12-dihydro-8H,10H-[1,4]oxazepino[4′,3′:1,2]imidazo[4,5-c]quinoline.
