実験手順

A mixture of 2-(aminomethyl)-1-benzyl-1H-imidazo[4,5-c]quinolin-4-amine (1.0 g, 3.3 mmol) and succinimido 3-(triphenylmethylthio)propanoate (2.2 g, 4.9 mmol) in dichloromethane (33 mL) was stirred overnight at room temperature. The reaction mixture was warmed and the solvent was removed under reduced pressure. Dichloromethane (30 mL) and trifluoroacetic acid (3 mL) were added and the mixture was stirred over the weekend. Additional trifluoroacetic acid was added. After 4 hours, the 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) followed by crystallization from ethyl acetate/acetonitrile. HRMS (ESI) calcd for C21H21N5OS+H 392.1545, found 392.1534.
