Reaction Steps

The title compound was prepared as a orange solid from 5-{[(2S)-2-(morpholin-4-ylmethyl)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 3-5 of Example 12. NMR (400 Mz, DMSO-d6): consistent. MS: (ES−) m/z 471 [M−H]. m.p.: 162.9-163.6° C.
