Reaction of 3-amino-5,5-dimethyl-2-cyclohexen-1-one with 3,4-dibromobenzaldehyde in an analogous manner to that described in Example 1 gave 9-(3,4-dibromophenyl)-3,4,6,7,9,10-hexahydro-3,3,6,6-tetramethyl-1,8(2H,5H)-acridinedione. Crystallization from absolute ethanol gave a pale yellow crystalline solid of melting point >290° C. (decomposition).
