YieldReaction ConditionsOperation in experiment
To 100 parts of 18 ° C ~ 22 ° C water was added 3.41 parts of 3-amino-4-methoxy benzoic acid and 4.71 Parts of 35percent hydrochloric acid. The resulting solution was cooled to 5 ° C. Thereto was added 1.46 parts of sodium nitrite, And the diazotization mixture for 2 hours to obtain a reaction solution. To 160 parts 18° C ~ 22 ° C water was added 12.22 parts of 7,7'-imino-bis (4-hydroxy-2-sulfonic acid), and treated with Sodium carbonate The pH of the mixture was adjusted to 7.0, and the mixture was cooled to 5 ° C. By the addition And sodium carbonate while maintaining the pH of 7.0 to 7.5, with two hours to the resulting solution was added the above reaction It should be added. Then, the mixture was further stirred for 5 hours. 80 parts of water were added to 3.76 parts of 3- amino-4-hydroxybenzenesulfonamide and 4.88 parts of 35percent hydrochloric acid, and the solution was cooled to 0 ° C. Its 1.46 parts of sodium nitrite was added, and the mixture was subjected to diazotization of 2 hours, thereby obtaining While the reaction solution was then maintained by addition of sodium carbonate to pH 7.0 to 8.0, with 2 H it was added to the above reaction solution was stirred for 5 hours after the. By the addition of sodium carbonate while pH was maintained at 8.0 to 9.0, and the solution was stirred for a further 2 hours. By the addition of 100 parts of Salt and the reaction solution was subjected to salting, and the precipitate was collected by filtration (i.e., the Compounds of formula (11) shown below represented).
