실험 절차

2.15 g (12.8 mmol) of ethyl 2-fluorobenzoate and 1.9 g (14 mmol) of potassium carbonate are successively added to a solution of 4 g (12.8 mmol) of tert-butyl (4′-hydroxybiphenyl-3-ylmethyl)methylcarbamate in 45 ml of dimethylacetamide. The reaction medium is refluxed for 48 hours, cooled, diluted with water and extracted with ethyl acetate. The organic phase is dried over sodium sulfate, filtered and concentrated under vacuum. The residue obtained is purified by chromatography on a column of silica eluted with an 80/20 heptane/ethyl acetate mixture. 3.1 g of ethyl 2-{3′-[(tert-butoxycarbonylmethylamino)methyl]biphenyl-4-yloxy}benzoate are obtained in the form of a colorless oil, in a yield of 53%.
