Benzoyl chloride → Rac-3-(4-benzoyl-piperazin-1-yl)-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one

Participants

Reaction Steps

The mixture of rac-6-chloro-3-(3-chloro-benzyl)-3-piperazin-1-yl-1,3-dihydro-indol-2-one (100 mg, 0.266 mmol), benzoyl chloride (37 mg, 0.266 mmol) and DIPEA (34 mg, 0.266 mmol) in acetonitrile (3 mL) was stirred at room temperature for overnight. Then the mixture was concentrated and the residue was purified with preparative HPLC to give 29 mg of rac-3-(4-benzoyl-piperazin-1-yl)-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one as a light orange solid. MS m/z 480 (M+H)+.
