To 2-(4-tert-Butyl-phenyl)-3-(4-nitro-phenyl)-propionic acid benzyl ester (8.6 g, 20.6 mmol) in 30 ml tetrahydrofuran, 20 ml methanol and 10 ml water was added sodium hydroxide (0.6 g, 24.7 mmol). The reaction mixture was stirred at 23° C. for 16 h, acidified with 4N hydrochloride acid, and concentrated. The residue was partitioned between ethyl acetate and water. The organic phase was washed with water, dried over magnesium sulfate, and concentrated to afford 2-(4-tert-Butyl-phenyl)-3-(4-nitro-phenyl)-propionic acid as a brownish oil (8.04 g, 100%).
