Versuchsvorschrift

To a stirred solution of 7-(benzyloxy)-N4-(tetrahydro-2H-pyran-4-ylmethyl)quinoline-3,4-diamine (51.2 g, 0.141 mol) and triethylamine (39.94 g, 0.395 mol) in dichloromethane (410 mL) at 0° C. was added a solution of chloroacetyl chloride (8.67 g, 76.80 mmol) in dichloromethane (40 mL) drop wise by addition funnel. The reaction was stirred at ambient temperature for 17 hours then heated to reflux for 6 hours. The crude mixture was cooled to ambient temperature and partitioned between water and dichloromethane (200 mL). The layers were separated and the aqueous layer extracted with dichloromethane (2×300 mL). The organic layers were combined, washed with brine (2×300 mL), dried over magnesium sulfate, filtered and concentrated under reduced pressure to provide 7-(benzyloxy)-2-(chloromethyl)-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinoline (61.7 g) as a brown solid.
