実験手順
Using the general method of Example 1 Part D, N4-(4-chlorobutyl)quinoline-3,4-diamine (˜35.75 mmol) was cyclized using triethyl orthopropionate (7.56 g, 42.9 mmol) in the presence of pyridine hydrochloride (0.41 g). The crude product was purified by chromatography (silica gel eluting with 95/5 dichloromethane/methanol) to provide 7.5 g of 1-(4-chlorobutyl)-2-ethyl-1H-imidazo[4,5-c]quinoline as a white powder.
