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, 3-iodo-7-methoxy-6-methyl-2-phenyl-chromen-4-one (78 mg, 0.20 mmol) was reacted to give the title compound (46 mg, 47%). 1H NMR (400 MHz, CDCl3): δ 8.20-7.98 (m, 1H), 7.44-7.15 (m, 9H), 6.86 (s, 1H), 5.05 (s, 1H), 3.94 (s, 3H), 2.61-2.44 (m, 4H), 2.33-2.28 (m, 3H), 2.14-1.98 (m, 1H), 1.91-1.75 (m, 1H), 1.49-1.12 (m, 9H).
