Participants

Reaction Steps

To a solution of N-{2-[benzoyl(3,3-diphenylpropyl)amino]ethyl}-4-indolinecarboxamide (77.0 mg) and 2-(tert-butylimino)-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (106 μL) in DMF (2.3 mL) was added ethyl bromoacetate (39 μL) and the mixture was stirred at ambient temperature for 40 hours. The resulting mixture was diluted with EtOAc (20 mL), washed successively with 1M HCl aqueous solution, saturated NaHCO3 aqueous solution and brine, dried over anhydrous MgSO4, filtered and evaporated in vacuo. The residue was purified by silica gel column chromatography (chloroform: MeOH=99:1) to afford ethyl {4-[({2-[benzoyl(3,3-diphenylpropyl)amino]ethyl}amino)-carbonyl]-2,3-dihydro-1H-indol-1-yl}acetate (87 mg) as an yellow syrup.
