Abstract

The invention comprises 2-styryl-4-chloro-6,7-phthaloyl-quinazoline of the formula <FORM:0683334/IV (b)/1> It is made by heating 3-cyan-2-cinnamoylamino-anthraquinone, (see Group IV (c)), with phosphorus pentachloride, preferably in a diluent such as nitrobenzene. Specification 642,129 is referred to.ALSO:2 - Styryl - 4 - chloro - 6,7 - phthaloylquinazoline (see Group IV (b)) is condensed with 4 - aminoanthraquinone - 2,1(N) - benzacridones, e.g. with halogen substitution products such as the 51- or 61-chloro- or 6,7-dichloro bodies, to give green vat dyes. Specification 642,129, [Group IV (b)], is referred to. 2 - Cinnamoylamino - 3 - cyananthraquinone is obtained by heating the corresponding 3-brom body with cuprous cyanide and pyridine in nitrobenzene, or by acylation of the corresponding 2-amino body with cinnamic acid chloride.
