반응 단계

To a slurry of cuprous oxide (12 g, 84 mmol) in pyridine (150 ml) were added a solution of 5-methyl-2-phenyl-4-(2-propynyl)oxazole in pyridine (150 ml) followed by a solution of 4-hydroxy-3-iodobenzaldehyde (35 g, 0.14 mol) in pyridine (100 ml). Bis(triphenyl-phosphine)palladium (II) chloride (0.50 g, 0.7 mmol) was then added as a solid and the mixture was heated to reflux overnight. The mixture was cooled and concentrated. The residue was taken up in ethyl acetate (250 ml +3×50 ml). The ethyl acetate solution was concentrated and the residue was extracted with hot cyclohexane. The hot solution was filtered and cooled and the solid was collected (29 g).
