Acetic Acid → 2,3-Diphenylquinoxalin-5-amine

Participants

Reaction Steps

1.53 g (10 mmol) of 2,3-diaminonitrobenzene and 2.00 g (9.6 mmol) of benzil were placed in four-necked flask, to which 30 g of a solvent of acetic acid and methanol at a mixing ratio of 1:1 was added for dissolution. Subsequently, the mixture was reacted at a reaction temperature of 70° C. for 2 hours. After the reaction, the solvent was removed and the resulting product was extracted with a silica gel column (ethyl acetate:hexane=1:1).
