Embodiment 1
[0019] Add 0.226g (1mmol) 2-(4-amino-2-hydroxyphenyl) benzoxazole and 0.097g (0.6mmol) carbonylimidazole to 20mL toluene, stir and reflux for 12h under the condition of drying and nitrogen protection , a large amount of pale yellow solid appeared, and the reaction was stopped. The crude product was obtained by filtration and purified by crystallization with DMSO to obtain 0.212 g of a yellow solid substance with a yield of 89%.
Embodiment 2
[0021] Add 0.226g (1mmol) 2-(4-amino-2-hydroxyphenyl) benzoxazole and 0.065g (0.4mmol) carbonylimidazole to 15mL toluene, stir and reflux for 15h under the condition of drying and nitrogen protection , a large amount of pale yellow solid appeared, and the reaction was stopped. The crude product was obtained by filtration and purified by crystallization with DMSO to obtain 0.162 g of a yellow solid substance with a yield of 85%.
