Reaction Steps
A mixture of 2-(2-methyl-4-(diethylamino)benzoyl)-3,4,5,6-tetrachlorobenzoic acid (44.9 g.), N,N,N',N'-tetraethyl-m-phenylenediamine (29.7 g.) and acetic anhydride (50 ml.) was heated (at 85°-90° C.) during three hours. The resulting crystalline product was washed with methanol, slurried in hot ethanol and washed again with methanol, affording 3-(2,4-bis(diethylamino)phenyl)-3-(2-methyl-4-(diethylamino)phenyl)-4,5,6,7-tetrachlorophthalide (I: X=Y4 =(CH3CH2)2N, Y2 =CH3, Z4 =Z5 =Z6 =Z7 =Cl) (34.1 g., m.p. 162°-164° C.).
