Procedure

To a solution of 3-butoxy-4-nitrobenzoic acid (City Chemicals) (2.5 g, 10.5 mmol) in methanol (10 mL) were added concentrated H2SO4 (1 g, 10.5 mmol). The reaction mixture was heated at reluxing for 2 h. The mixture was concentrated. The residue was partitioned between ethyl acetate and water. The organic layer was separated, and aqueous layer was extracted with ethyl acetate twice. The combined organic extract was washed with water, aqueous saturated NaHCO3 solution, brine, dried over MgSO4, and concentrated to give methyl 3-butoxy-4-nitrobenzoate as a brown oil (2.5 g, 95%).
