실험 절차
Chloroacetyl chloride (12 mL, 151 mmol) was dissolved in dichloromethane (30 mL) and added via addition funnel, over 20 minutes, to a stirring solution of N4-(tetrahydro-2H-pyran-4-ylmethyl)quinoline-3,4-diamine (35.3 g, 137 mmol) in dichloromethane (300 mL). The resulting solution was stirred at ambient temperature under nitrogen for 24 hours at which point the solution was heated to 40° C. for an additional 24 hours. The mixture was cooled to ambient temperature, diluted with dichloromethane (150 mL) and transferred to a separatory funnel. The organic layer was washed with water (2×200 mL) and brine (2×200 mL), dried over magnesium sulfate, filtered and concentrated under reduced pressure to provide 38.3 g of 2-(chloromethyl)-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinoline as a light brown solid.
