Versuchsvorschrift
(1-{4-[7-(2-Methoxy-ethyl)-4,8-dioxo-2-phenyl-7,8-dihydro-4H-pyrano[2,3-c]pyridin-3-yl]-phenyl}-carbamic acid tert-butyl ester: 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, 3-iodo-7-(2-methoxy-ethyl)-2-phenyl-7H-pyrano[2,3-c]pyridine-4,8-dione was reacted to give the title compound as a colourless oil (82 mg, 100%). LCMS (Method B): RT=4.63 min, [M+H]+=543.
