| titleOfInvention | Preparation method of N-substituted dibenzocarbazole compound |
| abstract | The invention belongs to the technical field of pharmaceutical and chemical intermediates and related chemistry, and relates to a preparation method of a novel N-substituted dibenzocarbazole compound. Alkynyl aniline and derivatives thereof are used as raw materials, and are subjected to serial cyclization reaction in an anhydrous organic solvent under the action of a catalyst, an oxidant and an additive to be converted into an N-substituted dibenzocarbazole compound. The preparation method of the N-substituted dibenzocarbazole compound has the advantages of few reaction steps, low raw material price, mild reaction conditions and convenient operation; and the obtained product has high yield and high purity, completely meets the quality requirement of serving as a pharmaceutical intermediate, and provides favorable conditions for industrial production of the pharmaceutical intermediate. |
