실험 절차

A solution of 3-[(4-hydroxy-phenylamino)-methylene]-1,3-dihydro-indol-2-one (0.945 g, 3.75 mmol) in 20 mL DMF is treated with potassium carbonate (777 mg, 1.5 equiv.) and 1-bromo-4-chlorobutane (1.1 equiv.). The reaction mixture is heated to 40° C. for 3 h. The reaction mixture is partitioned between EtOAc and water. The organic layer is collected and washed sequentially with H2O (1×), saturated aqueous NaHCO3 solution (1×), and brine (1×). The organic phase is dried and concentrated to give a solid. The solid is triturated with MeOH and collected by filtration to give the named compound as yellow solid (600 mg, 47%).
