To a stirring solution of ethyl (4-amino-1H-indol-1-yl)acetate (94 mg) in EtOH (7 mL) was added 1-(2-chloroethyl)-5-(diphenylmethyl)-2(1H)-pyridinone (70 mg) at ambient temperature. The reaction mixture was warmed to 50° C. After 24 hours, to the mixture was added water and the resulting mixture was extracted with EtOAc. The organic layer was washed with brine, dried over anhydrous sodium sulfate and evaporated in vacuo. The residue was purified by preparative thin-layer chromatography (chloroform:EtOAc=5:1) to give ethyl [4-({2-[5-(diphenylmethyl)-2-oxo-1(2H)-pyridinyl]ethyl}amino)-1H-indol-1-yl]acetate (45 mg).
