Synthesis of 4 - bromo - N - methyl - 1 (N)- 9 - anthracene and pyridone method (by machine translation)

The invention discloses a method for synthesizing 4 - bromo - N - methyl - 1 (N)- 9 - anthracene and pyridone method, ethanol and a small amount of tertiary butyl alcohol potassium input in the reactor, stirring to dissolve, the acylation material 1 - (N - methyl) b amido - 4 - bromo anthraquinone uniform stirring into the reactor, and then put into a small amount of calcium oxide, the beginning of the slow heating to a certain temperature, thermal insulation for a few hours, HPLC tracking, to be acylation material reaction finishes, can stop the insulation, to the room temperature, filtering and recycling the mother liquor, hot water washing, drying; the ring-closing reaction of the resulting product in the input to the sulfuric acid solution, beating a certain period of time at room temperature, filter, recovery of sulfuric acid solution, then with the same concentration of a sulfuric acid solution and the immersed material, filtering, the eluent with the mother liquid mixed collection, soft water washing materials to the washing water is neutral, discharging, drying. The invention mild reaction conditions, temperature and normal pressure reaction, the resulting product can reach 95%. (by machine translation)
