実験手順

Using the general method of Example 1 Part D, N4-(4-chlorobutyl)quinoline-3,4-diamine (119.1 g, 0.48 mole) was cyclized using trimethyl orthovalerate (93 g, 0.57 mol) in the presence of pyridine hydrochloride (1.1 g, 0.0095 mol) to provide 120 g of 2-butyl-1-(4-chlorobutyl)-1H-imidazo[4,5-c]quinoline as an ivory powder.
