Reaction Conditions

Reaction Steps

To a solution of 2-[5-(4-Chloro-phenyl)-2-methyl-thiophen-3-yl]-cyclopentane-1,3-dione (2.21 g, 7.25 mmol) in acetone (50 ml) was added potassium carbonate (1514 g, 10.87 mmol) followed by iodomethane (670 μl, 10.87 mmol) and the reaction heated to 40° C. for 6 hours. The solvent was then removed from the crude reaction mixture under reduced pressure and the residue partitioned between water (100 ml) and ethyl acetate (100 ml). The organic layer was separated, dry loaded onto silica and purified by flash chromatography to give 2-[5-(4-Chloro-phenyl)-2-methyl-thiophen-3-yl]-3-methoxy-cyclopent-2-enone (818 mg).
