実験手順
1.04 g of 2,3-diphenyl-5-nitroquinoxaline was dissolved in 30 g of dioxane, followed by purging with argon and further addition of 0.5 g of 5% Pd/C (hydrous). After sufficient purging with argon again, hydrogen was added and reacted at room temperature for 30 hours. After completion of the reaction, the reaction mixture was filtered and the solvent was removed, followed by isolation and purification with a silica gel column (ethyl acetate:hexane=1:3).
