Reaction Steps

The title compound was prepared as a light brown foam from 5-({(2S)-2-[(4-methylpiperazin-1-yl)methyl]pyrrolidin-1-yl}sulfonyl)-1H-indole-2,3-dione and 1-(chloromethyl)cyclopentanecarbonitrile (Syn. Comm. 20(12) 1757, 1990), using a procedure similar to that of steps 2-5 of Example 12. NMR (400 Mz, DMSO-d6): consistent. MS: (ES+) m/z 486.2 [M+H].
