Procedure

Potassium carbonate (0.12 g) and 1-(tert-butoxycarbonyl)piperidine (0.15 g) were added to a 1-methyl-2-pyrrolidone (2.0 mL) solution of methyl 2-(2-(benzyloxy)-5-(2-bromoethoxy)benzamido)-4-phenylbenzoate (0.40 g), followed by stirring at 90° C. for 45 minutes. The reaction mixture was cooled to room temperature, and then water and ethyl acetate were added thereto. The organic layer was separated, washed with a saturated aqueous solution of sodium chloride, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [Kanto Chemical Co., Inc., silica gel 60 (spherical), eluent: 80-0% hexane/ethyl acetate] to obtain 0.36 g of tert-butyl 4-(2-(4-(benzyloxy)-3-(2-(methoxycarbonyl)-5-phenylphenylcarbamoyl)phenoxy)ethyl)piperidine-1-carboxylate as a white solid.
