Reaction Steps

1.01 g (2.1 mmol) of 2,3-di(4-bromophenyl)-5-nitro-quinoxaline was dissolved in 30 g of dioxane, followed by purging well with argon, adding 0.3 g of 5% Pd/C (hydrous) and purging well with argon again. This system was purged with a hydrogen gas and reacted at room temperature for 24 hours. After completion of the reaction, the system was filtered. The resulting filtration residue was washed with acetone and then with dioxane and filtered again. The solvent was removed from the resulting filtrate and a reaction product was extracted with a silica gel column.
