Procedure

To a solution of 5-(4,4-dimethoxy-3-oxo-1-butenyl)-2,2'-bithiophene (50 mg) in tetrahydrofuran (2.5 ml) was added sodium borohydride (10 mg). The reaction mixture was stirred at room temperature for 1 hour. Ethyl acetate and water was added for partition. The organic layer was dried over anhydrous magnesium sulfate, concentrated and separated by silica gel chromatography. Light greenish oily product was obtained.
