To a solution of 2 g (12.18 mmol) 4-tert-butyl-1,2-diaminobenzene in 20 mL ethanol under argon at room temperature, was added 3.139 mL (15.83 mmol) ethyl glyoxalate (50% in toluene). The reaction mixture was stirred at room temperature for 4 h. The resulting suspension was filtered and washed with ethanol. The powder was dried to provide 257 mg (10.4%) of the title compound as a white solid. MS(m/e): 201.0 (M−H).
