Procedure

2M hexane solution (4.5 mL) of trimethylsilyldiazomethane was added to the mixture of 2-Nitro-3-methylbenzoic acid (1.6 g) and acetone (15 mL) and stirred for 3 hours. After removing the solvent, the residue was diluted with ethyl acetate and washed with 1M sodium hydrate aqueous solution, water and saturated aqueous solution of sodium chloride respectively. Then the obtained substance was concentrated and dried to obtain methyl 2-nitro-3-methylbenzoate.
