Reaction Conditions

Reaction Steps

Potassium carbonate (0.15 g) and azetidine hydrochloride (0.046 g) were added to a 1-methyl-2-pyrrolidone (1.3 mL) solution of methyl 2-(2-(benzyloxy)-5-(2-bromoethoxy)benzamido)-4-phenylbenzoate (0.25 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 [eluent: 100-90% chloroform/methanol] to obtain 0.088 g of methyl 2-(5-(2-(azetidin-1-yl)ethoxy)-2-(benzyloxy)benzamido)-4-phenylbenzoate as a light yellow oily substance.
