反应详情

A mixture of 5-bromo-N4-(2-methylpropyl)quinoline-3,4-diamine (1.0 g, 3.4 mmol), triethyl orthoformate (0.9 mL, 5 mmol), and pyridine hydrochloride (117 mg, 1.0 mmol) in acetonitrile (17 mL) was heated at reflux overnight. The reaction mixture was concentrated under reduced pressure, and the residue was purified by HPFC (eluting with chloroform:CMA in a gradient from 100:0 to 70:30) to provide 9-bromo-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline as a dark oil.
