PROCEDURE

实验过程

A mixture of 2-(4-dimethylamino)benzoyl)benzoic acid (8.07 g.), N,N,N',N'-tetraethyl-m-phenylenediamine (7.26 g.) and acetic anhydride (5 ml.) was heated (at 52° C.) during one and one-half hours. Addition of methanol (10 ml., then 15 ml.) afforded 3-(2,4-bis(diethylamino)phenyl)-3-(4-(dimethylamino)phenyl)phthalide (I: X=(CH3CH2)2N, Y2 =Z4 =Z5 =Z6 =Z7 =H, Y4 =(CH3)2N) (10.92 g., m.p. 117°-119° C.).
