Procedure

4,6-Dimethyl-2-nitro-phenylamine (10.6 g, 64.08 mmol) prepared in Step A was dissolved in acetic acid (150 mL). Sodium nitrite (5.3 g, 76.90 mmol) was added in drops thereto, and the mixture was stirred for 12 h. After completion of the reaction, the reaction mixture was diluted with ammonium hydroxide, extracted with dichloromethane, washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under reduced pressure, and the residue was purified by column chromatography to give the title compound (1.0 g, Yield 9%).
