実験手順

A mixture of N1-(3-aminopropyl)-2-methyl-1H-imidazo[4,5-c]quinoline-1,4-diamine hydrochloride (1.00 g, 3.26 mmol), succinimido 3-(triphenylmethylthio)propanoate (A. Bray et. al. Aust. J. Chem. 1990, 43, 629-634; 2.22 g, 4.89 mmol), triethylamine (0.45 mL, 3.26 mmol), dichloromethane (33 mL), and methanol (15 mL) was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure and the residue was purified by flash chromatography on silica gel (gradient elution with a solution of 2% ammonium hydroxide in methanol and chloroform). The purified compound was treated with trifluoroacetic acid (3 mL) and triethylsilane (2 mL) in dichloromethane (30 mL) at room temperature overnight. More trifluoroacetic acid was added and after an additional day the reaction was complete. The reaction mixture was concentrated under reduced pressure and purified by flash chromatography on silica gel (gradient elution with a solution of 2% ammonium hydroxide in methanol and chloroform) to yield 327 mg of N-{3-[(4-amino-2-methyl-1H-imidazo[4,5-c]quinolin-1-yl)amino]propyl}-3-mercaptopropanamide. MS (ESI) m/z 359 (M+H)+.
