실험 절차

To a solution of 1-[4-(3-cyano-1-cyclobutyl-6-hydroxy-1H-indol-2-yl)-phenyl]-3-isopropyl-urea (750 mg, 1.93 mmol) in 10 mL of acetonitrile is added anhydrous K2CO3 (800 mg, 5.79 mmol) and 1-bromo-3-chloropropane (382 μL, 3.86 mmol). After stirring overnight at 80° C., the reaction mixture is cooled and solvent is removed. The reaction is re-suspended in 100 mL of ethyl acetate. The organic phase is washed with 200 mL of H2O, and the aqueous phase is re-extracted 2× with 100 mL of ethyl acetate. The organic phases are combined, dried over MgSO4 and the solvent is removed to afford 769 mg (86%) of 1-{4-[6-(3-chloropropoxy)-3-cyano-1-cyclobutyl-1H-indol-2-yl]-phenyl}-3-isopropyl-urea as a tan powder.
