Versuchsvorschrift
1.53 g (10 mmol) of 2,3-diaminonitrobenzene and 2.00 g (9.6 mmol) of benzil were placed in a four-necked flask, and were dissolved by adding a 1:1 mixed solvent of acetic acid/methanol thereto. Thereafter, reaction was allowed at 70° C. for 2 hr. After the reaction, the solvent was removed, and the reaction product was extracted on a silica gel column (ethyl acetate:hexane=1:1).
