Embodiment 1
[0089] Synthesis of intermediate 2-(3-isoquinolyl)-6-methylbenzoxazole (A-1):
[0090]
[0091] Under the nitrogen protection system, put 25mmol of polyphthalamide (PPA) into the reaction system, raise the temperature to 100°C, add 25mmol of isoquinoline-3-carboxylic acid, 25mmol of 6-amino-m-cresol, At the same time, it was added to the above reaction solution, continued to heat up to 180°C, and reacted for 4 hours. After the reaction was completed, it was cooled, extracted with dichloromethane, and the solvent was evaporated by a rotary evaporator to obtain 2-(3-isoquinolinyl)- 6-methylbenzoxazole (A-1) 15.75mmol, yield 63%.
Embodiment 2
[0093] Intermediates A-2 and A-4 were synthesized according to the preparation method of intermediate A-1 above, and Table 1 is a summary of the reaction substances, generated substances and yields of Example 2 of the present invention.
[0094] Table 1 embodiment 2 reaction substance, generated substance and productive rate summary
[0095]
Embodiment 3
[0097] Synthesis of intermediate phenylpyridine metal iridium bridged ligand (B-1):
[0098]
[0099] Under a nitrogen protection system, weigh 22 mmol of 4-methyl-2,5-diphenylpyridine, iridium trichloride (IrCl 3 ·3H 2 O) Put 10mmol into the reaction system, add a mixed solution of 300ml ethylene glycol ethyl ether and 100ml pure water, reflux for 24 hours under nitrogen protection, then cool to room temperature, a precipitate precipitates, filter the precipitate with suction, rinse with water, and dry. Using dichloromethane as a detergent, silica gel column chromatography, concentrated and precipitated solids to obtain a novel iridium metal complex metal iridium bridging ligand (B-1) of oxazoles (9.2 mmol, 92%).
