| titleOfInvention | Method for producing dioxazine compound |
| abstract | An object of the present invention is to provide a method for producing a dioxazine compound having a higher yield than before and a chlorine-based by-product less likely to be produced. A dioxazine compound for closing a 3,6-bisarylamino-1,4-benzoquinone compound (C) which may be substituted with one or two halogen or acylamino groups at the 2,5-positions in a solvent. The method for producing a dioxazine compound (D), which comprises using an imidazolidinone compound or a pyrimidinedinone compound which may have an alkyl group on nitrogen and / or carbon as a solvent in the method for producing (D). And a compound (C) such as an arylamino compound (A) and a 3,6-dihalogeno-1,4-benzoquinone compound (1 to 2, which may be substituted with one or two halogen or acylamino groups at positions 2 and 5) ( The above-mentioned production method, wherein the ring-closure is carried out without exchanging the solvent after condensation using a product obtained by reacting B) with a solvent comprising the same compound as described above.
