Procedure

1,1′-Carbonyldiimidazole (3.20 g, 19.7 mmol) was added to 2-chloro-N4-(pyridin-3-ylmethyl)quinoline-3,4-diamine (5.09 g, 17.9 mmol) in THF (100 mL), and the resulting suspension was heated at 80° C. for three days. An analysis by LC/MS indicated the presence of starting material, and pyridine (100 mL) and additional 1,1′-carbonyldiimidazole (1 equivalent) were added. The reaction was stirred for two hours at 80° C., and additional 1,1′-carbonyldiimidazole (1 equivalent) was added. The reaction was stirred overnight at 80° C. and allowed to cool; a solid was present. Diethyl ether (50 mL) was added, and the solid was isolated by filtration and dried under vacuum to provide 4.2 g of 4-chloro-1-(pyridin-3-ylmethyl)-1H-imidazo[4,5-c]quinolin-2-ol as a gray solid.
