Yield:13297-17-1 94%

Reaction Conditions:

with triethylamine in ethanol at 45; for 2 h;

Steps:

Synthesis of 2-acetyl-3-methyl-quinoxaline 1,4-dioxide (2)

A mixture of benzofurazan oxide 1 (10.2 g, 0.075 mol) and acetylacetone (12 g, 0.12mol) in 25 mL ethanol was stirred at 45 °C, then triethylamine (4.55 g, 0.045 mol) was addedto the solution and the mixture stirred for 2 h at 45 °C. On cooling, a yellow precipitateformed, which was collected by filtration, washed with 10 mL 95 % ethanol and air-dried.Recrystallization of the yellow precipitate from 95 % ethanol afforded compound 2. Yield:15.38 g (94 %); m.p.: 154.2-154.8 °C (lit:4 153-154 °C).
