Embodiment 1
[0109] The synthesis of exemplary compound XX-1
[0110]
[0111] (1) Synthesis of compound X3
[0112] The following reactants and solvent were placed in the reactor.
[0113] Compound X1: 4.0 g (13 mmol)
[0114] Compound X2: 2.8g (13mmol)
[0115] Ethanol: 65ml
[0116] Next, the reaction solution was heated to 60° C., and then 10 ml of a 6M aqueous sodium hydroxide solution was added dropwise to the solution. After the addition was complete, the reaction solution was heated to 80°C and stirred at this temperature (80°C) for 2 hours. Next, the reaction solution was cooled to generate a precipitate, which was then filtered off. Next, the obtained precipitate was sequentially washed with water and ethanol, and then dried by heating at 80° C. under reduced pressure to prepare 6 g of Compound X3 as a dark green solid (yield: 89%).
[0117] (2) Synthesis of compound X5
[0118] The following reactants and solvent were placed in the reactor.
[0119] Compound X3: 5.0 g...
Embodiment 2
[0137] The synthesis of exemplary compound XX-2
[0138]
[0139] (1) Synthesis of Compound X8
[0140] The following reactants and solvent were placed in the reactor.
[0141] Compound X7: 10g (55mmol)
[0142] Compound X2: 12g (55mmol)
[0143] Ethanol: 200ml
[0144] Next, the reaction solution was heated to 60° C., and then 20 ml of a 6M aqueous sodium hydroxide solution was added dropwise to the solution. After the addition was complete, the reaction solution was heated to 80°C and stirred at this temperature (80°C) for 2 hours. Next, the reaction solution was cooled to generate a precipitate, which was then filtered off. Next, the obtained precipitate was sequentially washed with water and ethanol, and then dried by heating at 80° C. under reduced pressure to prepare 18 g of Compound X8 as a dark green solid (yield: 92%).
[0145] (2) Synthesis of compound X9
[0146] The following reactants and solvent were placed in the reactor.
[0147] Compound X8: 10g (28...
Embodiment 3
[0165] The synthesis of exemplary compound XX-5
[0166] Exemplary compound XX-5 was prepared by synthesis according to the same method as in Example 2, except that in Example 2(1), Compound X11 shown below was used instead of Compound X2.
[0167]
[0168] As a result of measuring the purity of the obtained compound by HPLC, it was confirmed that the purity was 99.5% or more.
[0169] In addition, the toluene solution of the exemplary compound XX-5 (1×10 -5 mol / L) emission spectrum. In this embodiment, the excitation wavelength is 500 nm. As a result, an emission spectrum having a peak intensity at 550 nm was obtained.
[0170] Furthermore, the compound was identified by measuring the molecular weight using JMS-T100TD (DART-TOF-MASS) manufactured by JEOL, Ltd.
[0171] DART-TOF-MASS: M+H=805.3
