The alcohol prepared above was dissolved in 7 mL of ethyl acetate and 75 mg of 10% Pd/C was added and the reaction mixture stirred under a hydrogen atmosphere for about 4 hours. The reaction mixture was filtered through Celite and concentrated in vacuo. The resulting residue was purified by preparative thin layer chromatography (10% ethyl acetate/hexane) to give 2-formyl-3-[(thiophene-2-yl)methyl]-5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene (94 mg, 62%) directly.
