Reaction Steps

To a solution of 3-hydroxy-4-methoxy-benzaldehyde (commercially available) (1 eq) was taken in dimethylformamide (10 mL), was added potassium iodide (0.1 eq) and potassium carbonate (2 eq). The reaction mixture was stirred at 70° C. and cyclopentyl bromide (2 eq) was added dropwise. The resulting reaction mixture was stirred at 70-80° C. for 16 hours. The reaction mixture was cooled and diluted with water, extracted with ethyl acetate and washed with saturated solution of sodium chloride. The organic solvent was removed under reduced pressure. The residue thus obtained was purified by column chromatography to furnish the title compound.
