Versuchsvorschrift
Following the procedure used to prepare {1-[4-(6-fluoro-4-oxo-2-phenyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester, 7-(2-hydroxy-ethyl)-3-iodo-2-phenyl-7H-pyrano[2,3-c]pyridine-4,8-dione was reacted to give the title compound (56 mg, 96%) as a colourless solid. LCMS (Method A): RT=4.41 min, [M+H]+=529.
