Participants

Reaction Steps

To the mixture of 2-chloro-1-piperidin-1-yl-ethanone (41 mg, 31 mmol) and KI (43 mg, 0.26 mmol) in dimethylformide (5 mL) was added rac-3-bromo-6-chloro-3-(4-chloro-benzyl)-1,3-dihydro-indol-2-one (100 mg, 0.26 mmol) prepared in example 76c. After stirring at room temperature for 2 h, water (10 mL) was added and the crude was extracted with ethyl acetate (3×20 mL). The combined organic solution was concentrated in vacuo. The residue was purified with preparative HPLC to give rac-6-chloro-3-(4-chloro-benzyl)-3-cyclohexylamino-1-(2-oxo-2-piperidin-1-yl-ethyl)-1,3-dihydro-indol-2-one as a white solid. MS: 514 (M+H)+.
