Procedure

To a solution of m-phenylenediamine (5.41 g) in pyridine (100 ml) is added dropwise methoxyacetyl chloride (10 ml). The mixture is stirred at room temperature for 2 hours, and thereafter, pyridine is distilled off under reduced pressure. To the residue is added water, and the mixture is extracted with chloroform. The organic layer is dried over anhydrous sodium sulfate and distilled under reduced pressure to remove the solvent. The resulting crude crystals are recrystallized from ethyl acetate-hexane to give the title compound (9.89 g) having the following physical properties.
