Reaction Steps

2.2 g (5.1 mmol) of 2,3-di(2-thienyl)-5-(4-nitrophenyl)aminoquinoxaline was dissolved in 50 ml of tetrahydrofuran, and a reaction container was purged with nitrogen. Thereafter, 0.7 g of 5% Pd/C (hydrous) was added, followed by sufficient purging with nitrogen again. This system was purged with hydrogen, followed by reaction at room temperature for 5 hours. After completion of the reaction, the system was filtered, and the resulting filtration residue was washed with tetrahydrofuran and filtered again. The solvent was removed from the resulting filtrate, and a reaction product was extracted with a silica gel column.
