실험 절차

A mixture of 8-(3-chloropropoxy)-2-(methoxymethyl)-1-propyl-1H-imidazo[4,5-c]quinolin-4-amine (0.20 g, 0.55 mmol, 1 equivalent), potassium carbonate (4 equivalents), and 1-(2-pyridyl)piperazine (1.1 equivalents) in DMF (5 mL) was heated at 70° C. overnight. The reaction mixture was allowed to cool to room temperature and was poured onto ice (50 g). After the mixture was stirred for 3 hours, a brown solid was isolated by filtration. The crude product was purified by chromatography on a HORIZON HPFC system (silica gel, gradient elution with 0-30% CMA in chloroform), followed by recrystallization from acetonitrile to afford 0.065 g of 2-(methoxymethyl)-1-propyl-8-[3-(4-pyridin-2-ylpiperazin-1-yl)propoxy]-1H-imidazo[4,5-c]quinolin-4-amine as off white crystals, mp 196-197° C.
