A solution of bis(1,1-dimethylethyl)(4-methyl-2-nitrophenyl)propanedioate (D38, 660 mg, 1.88 mmol) in ethyl acetate (25 mL) was treated with 10% Pd/C (0.5 g) and shaken under hydrogen at atmospheric pressure and room temperature for 20 hours. The mixture was filtered through Kieselguhr and the filtrate concentrated under vacuum to afford the title compound as a colourless oil (606 mg, 100%).
