Versuchsvorschrift
In a 500 ml two-neck flask, N-(t-butylphenyl) carbazolone (Compound F, 13 g) and diphenylether (100 ml) were mixed, and the 10% Pd/C (13 g) was added thereto. This reaction solution was refluxed and stirred for 30 minutes to 1 hour. When the reaction was completed, 80% of diphenylether was removed by distillation under reduced pressure, and a catalyst was removed using celite. The filtrate was washed again with ethylacetate. The filtrate was concentrated under reduced pressure and separated using a column chromatography, thereby obtaining 11 g of N-(t-butylphenyl)hydroxycarbazole (Compound G).
