Reaction Conditions

Reaction Steps

To a solution of 3-chloro-4-dimethylcarbamoylthiophenylacetic acid methyl ester (129 mg, 0.3991 mmol) in 0.75 mL methanol was added a 0.5M solution of sodium methoxide in methanol. This mixture was heated to 70° C. for 90 minutes. After cooling to ambient temperature, a solution of 7-(3-bromopropoxy)-4-ethyl-8-propylcoumarin (Step D) in 1.2 mL methanol was added dropwise. The mixture was heated to 70° C. for 16 hours. The reaction mixture was concentrated in vacuo and diluted with ethyl acetate. The organic mixture was washed with water, brine, dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash chromatography on silica gel (20% ethyl acetate/hexane) to provide the title compound.
