Procedure

10 g of 9-{4-[(5-methyl-2-phenyloxazole-4-yl)methoxy]-3-methoxybenzyl}-4-(allyloxy)-9H-carbazole was suspended in mixed solution (70 mL) of tetrahydrofuran-ethanol=4:1, 986 mg of triphenylphosphine, 84 mg of palladium acetate, and 2.1 mL of formic acid were added, and refluxed for 5 hours. The reaction mixture was allowed to cool, and then concentrated in vacuo, and the residue was crystallized from 10 mL of ethanol. The crystalline precipitate was isolated by filtration, washed with ethanol, dried under reduced pressure, and 8.96 g of the subject compound was prepared as pale yellow crystal.
