反応手順
A mixture of 2-(4-(dimethylamino)benzoyl)benzoic acid (26.8 g.), N,N,N',N'-tetramethyl-m-phenylenediamine (16.4 g.) and acetic anhydride (80 g.) was heated (to 95° C.) during one hour, cooled and poured into dilute hydrochloric acid. The resulting mixture was basified. Recrystallization of the resulting solid from a mixture of toluene and hexane afforded 3-(2,4-bis(dimethylamino)phenyl)-3-(4-(dimethylamino)phenyl)phthalide (I: X=Y4 =(CH3)2N, Y2 =Z4 =Z5 =Z6 =Z7 =H) (m.p. 190°-194° C.).
