Procedure
Essentially following the procedures described in Intermediate 4, but using 4-nitro-1,3-dihydro-2H-indol-2-one from Step A in place of 5-nitro-1′-{[2-(trimethylsilyl)ethoxy]methyl}-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one, the title compound was obtained. MS: m/z=149 (M+1).
