4-Chloro-6,7-dimethoxyquinoline → HCID 22132715, compound

Participants

Reaction Conditions

Reaction Steps

4-Chloro-6,7-dimethoxyquinoline (112 mg) and 4-hydroxyphenyl 2-naphthyl ketone (124 mg) obtained in Example 36 were mixed and stirred at 180° C. for 30 minutes. The reaction mixture was partitioned between saturated aqueous sodium hydrogen carbonate and chloroform, and then the chloroform layer was dried with anhydrous magnesium sulfate. After removing the solvent by reduced-pressure distillation, a portion (50 mg) of the resulting residue (227 mg) was purified by thin layer chromatography on silica gel eluting with chloroform/ethyl acetate (5/1) to obtain 11 mg of the title compound (yield: 23%).
