YieldReaction ConditionsOperation in experiment
200 ml beaker<strong>[98-32-8]2-aminophenol-4-sulfonamide</strong>(Manufactured by Tokyo Chemical Industry Co., Ltd.) 6.6 parts and water 50 parts were charged,35percent hydrochloric acid water was added dropwise to adjust the pH to 1.0 or less.7.3 parts of a 40percent sodium nitrite aqueous solution was added dropwise at a liquid temperature of 10 ° C. or lower,And the mixture was stirred at 10 ° C. or less for 1 hour.Next, this reaction solution was added to a pyridone compound represented by the following formula (101)8 parts were dissolved in 100 parts of water,While maintaining the pH at 8.5 to 9.0, at a temperature of 10 ° C. or lower, in a suspension adjusted to pH 9 with 15percent sodium carbonate aqueous solution. After completion of the dropwise addition, the reaction solution was stirred overnight. Subsequently, the reaction solution was heated to 60 to 70 ° C.,The mixture was stirred while maintaining the pH at 6 to 7, and the precipitated crystals were collected by filtration and dried to obtain 6.1 parts of a dye intermediate represented by the following formula (102).
