Versuchsvorschrift
2-(4-Fluorophenyl)-N-methyl-6-(methylsulfonamido)-5-vinylfuro[2,3-b]pyridine-3-carboxamide is prepared by analogy to 2-(4-Fluorophenyl)-N-methyl-6-(methylsulfonamido)-5-(prop-1-en-2-yl)furo[2,3-b]pyridine-3-carboxamide, step A of Example 33. Potassium vinyltrifluoroborate may be used as the coupling partner.
