実験手順
A mixture of 2-(4-(diethylamino)benzoyl)-3,4,5,6-tetrachlorobenzoic acid (8.70 g.), N,N,N',N'-tetramethyl-m-phenylenediamine (3.61 g.) and acetic anhydride (5 ml.) was heated (to 90° C.). Addition of methanol (10 ml.) and slurrying the resulting product with methanol afforded 3-(2,4-bis(dimethylamino)phenyl)-3-(4-diethylamino)phenyl)-4,5,6,7-tetrachlorophthalide (I: X = (CH3)2N, Y2 = H, Y4 = (CH3CH2)2N, Z4 = Z5 = Z6 = Z7 = Cl) (5.60 g., m.p. 206°-207.5° C.).
