[0255] -Manufacture of Compound 1-1

[0256] Production of [Compound A]

[0257]

[0258] Add compound A-1 (Benzenesulfonate Dichlorosulfofluorescein, benzenesulfonate dichlorosulfofluorescein) (3g, 7.40mmol, 1eq), compound A-2 (2-(Ethylamino)ethanol, 2 -(Ethylamino)ethanol) (5.28g, 59.22mmol, 8eq), deionized water (DI-water) 50g, and stirred at 100 degreeC. Then, the reaction was carried out overnight (12 hours). The reaction was terminated by quenching in 1M HCl solution (Solution), and NaCl (sodium chloride, sodium chloride) was added to precipitate the reactant. The generated precipitate was filtered under reduced pressure, and then dried in an oven (oven) at 80°C. After drying, in order to remove NaCl between the products, it was dissolved in DMF (Dimethylformamide, dimethylformamide) and filtered, and the filtrate was quenched (quenching) in diethyl ether, and the It was filtered and dried to obtain compound A (2.88 g, 5.64 mmol, 76%).
