실험 절차

A mixture of 1.04 g (0.0042 mol) of 5,8-dimethylindeno[2,1-b]indol-6(5H)-one and 1.12 mL (0.0224 mol) of hydrazine monohydrate in 20 mL of diethylene glycol was stirred at 80° C. for 1 h and then refluxed for 1 h. The resulting mixture was cooled to r.t., treated with a solution of 1.2 g (0.0214 mol) of KOH in 5 mL of water and then it was refluxed for 2 h. The resulting mixture was poured into 100 mL of water, the precipitate was filtered, washed 5 times with 50 mL of water and dried. Yield 0.84 g (86%) of greenish solid.
