{1-[4-(6-Fluoro-4-oxo-2-phenyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester → {1-[4-(6-Methoxy-7-methyl-4-oxo-2-phenyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester

Participants

Reaction Steps

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-6-methoxy-7-methyl-2-phenyl-chromen-4-one (78 mg, 0.20 mmol) was reacted to give the title compound (40 mg, 41%). 1H NMR (400 MHz, CDCl3): δ 7.56 (s, 1H), 7.41-7.17 (m, 10H), 5.04 (s, 1H), 3.94 (s, 3H), 2.60-2.46 (m, 4H), 2.39-2.35 (m, 3H), 2.13-2.00 (m, 1H), 1.90-1.76 (m, 1H), 1.48-1.10 (m, 9H).
