Procedure

A mixture of the 6-nitropyridoquinoxalinedione (0.1 g, 0.38 mmol), phenylisothiocyanate (70 μL), triethylamine (70 μL) in DMF (5 mL) was stirred at 60° C. for 24 hours. The mixture was poured onto water and allowed to stand. The precipitate was collected by filtration, washed with water and ether, and dried in vacuo to give product (130 mg) as a beige solid; mp 270-274° C., nmR, IR.
