HCID 57897365(+/-)-2'-Oxo-1',2',6,8-tetrahydrospiro[cyclopenta[g]quinoline-7,3'-pyrrolo[2,3-b]pyridine]-2-carbaldehyde

Procedure

Essentially following the procedures described for Intermediate 10, but using (±)-5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (described in Intermediate 4) in place of (S)-5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one, the title compound was obtained. MS: m/z=316 (M+1).
