A solution of 3-(4-formyl-3,5-dimethylphenyl)-acrylic acid tert-butyl ester (210 mg) in CH2Cl2 (8 mL) was hydrogenated at 1 atm over 10% Pd/C (21 mg) for 4 h. The catalyst was filtered and the filtrate concentrated to give 3-(4-formyl-3,5-dimethylphenyl)-propionic acid tert-butyl ester as a yellow solid. MS (ESI)m/z 286 (M+H).
