Reaction Steps

2.02 g of 2,3-di(4-methylphenyl)-5-nitroquinoxaline was dissolved in 30 g of dioxane, followed by purging with argon and adding 0.6 g of 5% Pd/C (hydrous). After purging with argon again, the system was purged with hydrogen for reaction at room temperature for 18 hours. After completion of the reaction, the system was filtered. The filtration residue was washed with acetone and then with dioxane and filtered again. The solvent was removed from the resulting filtrate, followed by extracting a reaction product by use of a silica gel column.
