Abstract

PURPOSE:To obtain in high yield a dioxazine compound useful as a dye/pigment by condensation reaction between a 2,5-dihalogeno-1,4-benzoquinone and a 9- alkyl-3-aminocarbazole followed by cyclization under heating to effect reduction of by-products. CONSTITUTION:A compound of formula I (X is a halogen) is condensed with a compound of formula II (R is H or a 1-8C alkyl) in an inert organic solvent in the presence of an acid coupler followed by cyclization under heating in the presence of a cyclizing agent to obtain the objective chlorine-free dioxazine compound of formula III in high purity.
