ethyl 5-iodo-3-{[2-(phenoxymethyl)morpholin-4-yl]sulfonyl}-1-(phenylsulfonyl)-1H-indole-2-carboxylate → (R)-5-Iodo-3-{[2-(phenoxymethyl)morpholin-yl]sulfonyl}-1H-indole-2-carboxamide

Participants

Reaction Steps

Using the same procedures described for Example 23, replacing the product from Step A of Example 22, ethyl(±)-5-chloro-3-{[2-(phenoxymethyl)morpholin-4-yl]sulfonyl}-1-(phenylsulfonyl)-1H-indole-2-carboxylate, with ethyl(±)-5-iodo-3-{[2-(phenoxymethyl)morpholin-1-yl]sulfonyl}-1-(phenylsulfonyl)-1H-indole-2-carboxylate, the second-eluting enantiomer of ethyl 5-iodo-3-{[2-(phenoxymethyl)morpholin-4-yl]sulfonyl}-1-(phenylsulfonyl)-1H-indole-2-carboxylate was converted to the titled compound after purification by preparative reversed phase HPLC. Proton NMR for the product was consistent with the titled compound. ESI+MS: 542.82 [M+H]+.
