A method for preparing the hydroxamic acid comprises the steps of: (a) reacting an anhydrous compound synthesized by reacting ethyl chloroformate with piperonic acid using pyridine or N-methyl morpholine as a solvent with methyl 4-amino benzoate or 4-amino phenyl acetic acid ethyl ester at a temperature of 10-20 deg.C using pyridine or N-methyl morpholine as a solvent to prepare a benzamide compound; (b) reacting the benzamide with an alkyl halide selected from the group consisting of bromomethane, bromoethane, bromopropane, bromo isopropane, bromo butane, and bromo tert-butane to substitute an amide bond of the benzamide with an alkyl group; (c) hydrolyzing methyl ester in the benzamide obtained from the step(a) or the benzamide compound obtained from the step(b) to prepare an acid and reacting the acid with ethyl chloroformate using pyridine or N-methyl morpholine as a solvent to covert the acid into an anhydrous compound; and (d) reacting the anhydrous compound with hydroxyl amine chloride or N-methyl hydroxyl amine chloride at a temperature of 0-10 deg.C using pyridine or N-methyl morpholine as a solvent to obtain the product of the formula(1). An agent for anti-obese, treating diabetes or hyperlipidemia comprises the hydroxamic acid.
