5-amino-1,3-dihydrospiro[indene-2,3'-pyrrolo[2,3-b]pyridin]-2'(1'H)-one → N2-(2-Oxo-2,3-dihydro-1H-indol-4-yl)-N-(2'-oxo-1,1',2',3-tetrahydrospiro[indene-2,3'-pyrrolo[2,3-b]pyridin]-5-yl)glycinamide

Participants

Reaction Steps

Essentially following the procedures described for Example 1, but using N-(2-oxo-2,3-dihydro-1H-indol-4-yl)glycine (described in Intermediate 8) in place of 3-phenylpropionic acid and (−)-5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (described in Intermediate 4) in place of (+)-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=440 (M+1). HRMS: m/z=440.1750; calculated m/z=440.1717 for C25H22N5O3.
