Synthetic example 1
[0528] 20 parts of a compound represented by the following formula (1x) and 200 parts of N-ethyl-o-toluidine (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed under light-shielding conditions, and the resulting solution was stirred at 110° C. for 6 hours. After cooling the obtained reaction liquid to room temperature, it added to the liquid mixture of 800 parts of water and 50 parts of 35% hydrochloric acid, and stirred at room temperature for 1 hour, and crystals precipitated. The precipitated crystal was collected as a suction-filtered residue, and then dried to obtain 24 parts of a compound represented by formula (1-24) (hereinafter referred to as "xanthene dye 1"). The yield was 80%.

Synthetic example 2
[0534] In the flask that is equipped with cooling tube and stirring device, throw into the mixture (commercial name ChugaiAminolFastPinkR of the compound shown in formula (A0-1) and the compound shown in formula (A0-2) 15 parts, 150 parts of chloroform and To 8.9 parts of N,N-dimethylformamide, 10.9 parts of thionyl chloride were added dropwise while maintaining the temperature below 20°C with stirring. After completion of the dropwise addition, the temperature was raised to 50°C, maintained at the same temperature for 5 hours to allow a reaction, and then cooled to 20°C. While maintaining the cooled reaction solution at 20° C. or lower with stirring, a mixed solution of 12.5 parts of 2-ethylhexylamine and 22.1 parts of triethylamine was added dropwise. Then, it stirred at the same temperature for 5 hours, and made it react. Next, the solvent was distilled off from the obtained reaction mixture using a rotary evaporator, and a small amount of methanol was added thereto, follo...

[0537] The following reactions were carried out under nitrogen atmosphere. After injecting 36.3 parts of potassium thiocyanate and 160.0 parts of acetone into the flask equipped with the cooling tube and the stirring device, it stirred at room temperature for 30 minutes. Then, 50.0 parts of benzoyl chloride (manufactured by Tokyo Chemical Industry Co., Ltd.) was added dropwise over 10 minutes. After completion of the dropwise addition, the mixture was further stirred at room temperature for 2 hours. Then, after ice-cooling the reaction mixture, 45.7 parts of N-ethyl-o-toluidine (manufactured by Tokyo Chemical Industry Co., Ltd.) was added dropwise. After completion of the dropwise addition, the mixture was further stirred at room temperature for 30 minutes. Then, after ice-cooling the reaction mixture, 34.2 parts of 30% sodium hydroxide aqueous solution were added dropwise. After completion of the dropwise addition, the mixture was further stirred at room temperature for 30...
