Procedure

2.5 g (8.2 mmol) of 7-amino-1-(2-ethylbutyl)-6-nitro-2,3(1H,4H)-quinoxalinedione and 1.1 g (8.2 mmol) of 2,5-dimethoxytetrahydrofuran were refluxed in 100 ml of acetic acid for 1 h. The mixture was then poured into ice-water, and the precipitate was filtered off with suction, washed with water and dried to yield 0.8 g (31%) of the product. Melting point 154°-155° C.
