실험 절차

To a conc. chloric acid (10 ml) suspension of 2-tert-butyl-5-nitroaniline (WO 02055501) (1.94 g, 10.0 mmol) was added the H2O (5 ml) solution of sodium nitrite (690 mg, 10.0 mmol) at 0° C. The mixture was stirred at 0° C. for 20 min and to the mixture was then added the conc. chloric acid (10 ml) solution of copper chloride (900 mg, 10.0 mmol) at 70° C. The reaction mixture was stirred at 70° C. for 20 min and the resulting precipitate was collected by filtration, washed with H2O and dried under reduced pressure to furnish furnish 1.76 g (78% yield) of the title compound as a white solid.
