Reaktionsschritte
To a solution of 0.50 g 4-hydrox-phenylaniline, 0.83 g of 2-(5-methyl-2-phenyl-1,3-oxazol-4-yl)ethan-1-ol and 1.06 g of triphenylphosphine in 20 ml of THF was added at 0° C. a solution of 0.82 g of diisopropyl azodicarboxylate in 10 ml of THF over 30 min and stirring was continued at 22° C. for 5 h. The mixture was evaporated and the residue purified by chromatography (SiO2, n-hexane/AcOEt 6:1) to give 0.62 g of the title compound as a colorless solid. MS: (M+H)+ 371.4.
