Procedure

A mixture of 2-(4-(diethylamino)benzoyl)-3,4,5,6-tetrachlorobenzoic acid (8.70 g.), N,N,N',N'-tetraethyl-m-phenylenediamine (4.85 g.) and acetic anhydride (5 ml.) was heated (to 90° C.). Addition of methanol (10 ml.) and slurrying the resulting product with methanol (20 ml.) afforded 3-(2,4-bis(diethylamino)phenyl)-3-(4-(diethylamino)-phenyl)-4,5,6,7-tetrachlorophthalide (I: X = Y4 = (CH3CH2)2N, Y2 = H, Z4 = Z5 = Z6 = Z7 = Cl) (7.85 g., m.p. 196°-197° C.).
