반응 단계
In accordance with the process of Example 1, the aqueous solution containing a sodium carbonate and 2-[4,4'-bis-(dimethylamino)benzhydryl]-5-dimethylaminobenzoic acid and cobalt complex of 1-[(2-hydroxynaphthyl)azo]-2-hydroxybenzene-5-sulfonic acid [I], was heated at 90° C. and 36 wt. parts of air was fed into it under vigorously stirring during 15 hours and the precipitate was separated by a filtration and washed with a dilute aqueous solution of sodium hydroxide and with water to obtain 39.4 wt. parts of 3,3-bis-(4-dimethylaminophenyl)-6-dimethylaminophthalide having a melting point of 181° to 183° C.
