Procedure

A solution of pyridine-3-isothiocyanate (0.136 g, 1.0 mmol) in chloroform (5 mL) was added at ambient temperature to a solution of 1-(4-aminobutyl)-2-phenyl-1H-imidazo[4,5-c]quinolin-4-amine (0.331 g, 1.0 mmol) in a mixture of chloroform (25 mL) and pyridine (5 mL). The reaction mixture was maintained at ambient temperature over the weekend. The reaction was quenched with ethanol and then concentrated tinder vacuum to provide an off-white solid. This material was purified by flash chromatography (silica gel, eluting with 10% methanol in dichloromethane). The pure fractions were combined and concentrated under vacuum to provide 0.2 g of N-[4-(4-amino-2-phenyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]-N′-(3-pyridyl)thiourea as a white solid, m.p. 118-120° C. Mass spec M+1=468.3. Analysis: Calculated for C26H25N7S: %C, 66.79; %H, 5.39; %N, 20.97; Found: %C, 64.29; %H, 5.46; %N, 20.06.
