A mixture of 4-chloro-2-methyl-quinolin-8-ol (2.0 g, 10 mmol) and imidazole (3.53 g, 51.8 mmol) in dioxane (20 mL) was heated to reflux for 28 h. The solvent was removed in vacuo and the residue was purified by flash chromatography on silica gel (elution with DCM/methanol 10:1) to give the title compound. MS (m/z): 226.3 [M+H+].
