Participants

Reaction Steps

2.0 g of 2,3-dihydroxy-5-nitroquinoxaline was dissolved in 100 g of a 1:1 methanol and dioxane solvent, after which the reaction system was well purged with argon, followed by further addition of 1 g of 5% Pd/C (hydrous). Thereafter, the system was purged with hydrogen, followed by reaction at room temperature for 20 hours. After completion of the reaction, the reaction product was dispersed in a solution of 6.00 g of potassium carbonate in 130 ml of water and then dissolved therein. 35% hydrochloric acid was gradually added to the solution obtained after filtration thereby obtaining a precipitate.
