Procedure

At room temperature, 1 g of palladium on carbon (10%) was added to a solution of 12 g (51.42 mmol) of methyl 2,2-dimethyl-3-(3-nitrophenyl)propanoate in 200 ml of ethanol, and the mixture was hydrogenated under atmospheric pressure for 12 hours. After the reaction had gone to completion (monitored by TLC; mobile phase cyclohexane/ethyl acetate 1:1), the reaction solution was filtered through kieselguhr and the filtrate was concentrated under reduced pressure. The crude product was purified chromatographically on silica gel (mobile phase cyclohexane/ethyl acetate 4:1→1:1). This gave 9.2 g (44.39 mmol, 86% of theory) of the title compound.
