[0206] [Preparation example 1] Synthesis of core (Core) 1
[0207] (4-chlorophenyl)(2-phenylbenzo[d] Azol-6-yl)methanone ((4-chlorophenyl)(2- Synthesis of phenylbenzo[d]oxazol-6-yl)methanone)
[0208]
[0209]Add 6-bromo-2-phenylbenzo[d] to the reactor oxazole (6-bromo-2-phenylbenzo[d]oxazole) (100g, 364.8mmol) was poured into 1000ml of THF, stirred, added to a dry ice bath, and the internal temperature was set to -78°C. After slowly injecting 2.5M n-BuLi (133.7 ml, 334.4 mmol) with a syringe, the mixture was stirred for 30 minutes. 4-Chlorobenzaldehyde (4-chlorobenzaldehyde) (42.7g, 304mmol) was dissolved in 100ml of THF and slowly added dropwise. Slowly warm up to room temperature. After concentrating the reaction, add I 2 (203.7g, 802.6mmol), K 2 CO 3 (166.4g, 1203.8mmol), t-BuOH800ml, heated to reflux for 7 hours. After the reaction, extract with ethyl acetate, then add MgSO 4 filter.

[0254] [Synthesis Example 1] Synthesis of Compound Inv 1
[0255]
[0256] The core 1 (5g, 8.9mmol) of [Preparation Example 1] and 2-chloro-4,6-diphenyl-1,3,5-triazine (2-chloro-4,6-diphenyl-1,3 ,5-triazine) (2.86g, 8.9mmol) and Pd (PPh 3 ) 4 (0.3g, 0.26mmol), K 2 CO 3 (3.7g, 26.7mmol) was added to toluene 80ml, EtOH 20ml, H 2 O 20ml, heated to reflux for 12 hours. After the reaction, extract with dichloromethane, add MgSO 4 filter. After the solvent of the filtered organic layer was removed, the target compound Inv 1 (4.3 g, yield 72%) was obtained by column chromatography.

[0258] [Synthesis Example 2] Synthesis of Compound Inv 12
[0259]
[0260] Using 2-chloro-4,6-bis(dibenzo[b,d]furan-3-yl)-1,3,5-triazine (2-chloro-4,6-bis(dibenzo[b,d] ]furan-3-yl)-1,3,5-triazine) (4.7g, 10.68mmol) instead of 2-chloro-4,6-diphenyl-1,3,5-triazine, in addition, implement The target compound Inv 12 (5.6 g, yield 74%) was obtained by the same procedure as [Synthesis Example 1].
