Potassium Carbonate → HCID 69372123, compound

Participants

Reaction Steps

A suspension of 138.6 mg (0.34 mmol) of 7-cyanoimidazo[4,5-g]quinolin-8-yl(3,4,5-trimethoxyphenyl)formamide and 229.1 mg (1.66 mmol) of potassium carbonate in 10 mL of methanol is refluxed for 2 hours. After cooling, the solution is diluted with water and neutralized to pH 7 with AcOH. The precipitate is collected by filtration and washed with water, diethyl ether and ethyl acetate. After drying in vacuo, this yields a crude product. Purification of the crude product by flash chromatography (elution with 95:5 methylene chloride/methanol) yields 87.3 mg (68.5%) of the final product as a yellow solid, mp>260° C.,
