Embodiment 1
[0029] Example 1: Synthesis of 2-(5-(4'-(diphenylamino)-[1,1'-diphenyl]-4-)oxazol-2-yl)-6-methylphenol
[0030]Under nitrogen protection, o-methylphenoxyacetamide (0.2mmol, 33.2mg), 4'-(5-oxazolyl)-N,N-diphenyl-[1,1'-diphenyl] -4-amine (0.3mmol, 116.4mg), dichloro(pentamethylcyclopentadienyl) rhodium (III) dimer (5.0mol%, 6.4mg), silver hexafluoroantimonate (20mol%, 13.6mg), pivalic acid (0.4mmol, 41.0mg), cesium pivalate (0.16mmol, 38mg), silver carbonate (0.08mmol, 22mg) were added to a reaction tube equipped with a magnetic stirrer, and added under nitrogen N,N-Dimethylformamide (1.0 mL) was stirred at room temperature for 5 minutes, and then reacted at 140° C. for 24 hours. After the reaction was completed, the reaction tube was cooled to room temperature, ethyl acetate was added to dilute the reaction system, filtered through diatomaceous earth, and washed with ethyl acetate, the filtrates were combined, the solvent was removed under reduced pressure, and the residue was...
