반응 단계
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.).
