Procedure

3.53 g of 2-bromobenzoic acid, 2.23 g of copper iodide, 1.63 g of N,N-dimethylglycine hydrochloride, and 15.2 g of cesium carbonate were added to 1,4-dioxane (50 mL) suspension of 5.74 g of 9-{4-[(5-methyl-2-phenyloxazole-4-yl)methoxy]-3-methoxybenzyl}-9H-carbazole-4-ol, and refluxed overnight. 1 N hydrochloric acid was added to the reaction mixture, extracted with ethyl acetate, and washed with brine. The extract was dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated in vacuo, the residue was purified by silica gel chromatography (ethyl acetate:n-hexane=2:1), and 1.4 g of the subject compound was prepared as white crystal.
