실험 절차

Under ice-cooling, potassium carbonate (0.19 g) and tert-butyl 2-(5-(bromomethyl)-2-(methoxymethoxy)benzamido)-4-phenylbenzoate (0.12 g) were sequentially added to an acetone (1.8 mL) suspension of 1-propylpiperazine dihydrochloride (0.13 g), followed by stirring at room temperature for 5 hours and 30 minutes. The solvent was evaporated under reduced pressure, and a saturated aqueous solution of sodium bicarbonate and chloroform were added to the residue. The organic layer was separated 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: 100-90% chloroform/methanol] to obtain 0.088 g of tert-butyl 2-(2-(methoxymethoxy)-5-((4-propylpiperazin-1-yl)methyl)benzamido)-4-phenylbenzoate.
