Procedure

To a solution of diethyl 2-(2-chloro-4-nitrophenyl)malonate (step 1, 7.6 g, 24.2 mmol) in methanol (18 ml) was added 6M-NaOH (12 ml) and stirred for 1 h at 50° C. The reaction was quenched by the addition of saturated citric acid aqueous solution (16 ml) and water. The organic layer was extracted with ethyl acetate (2×50 ml), washed with brine, dried (MgSO4) and concentrated to give 4.52 g (87%) of title compound as light yellow solid.
