実験手順
Following the procedure used to prepare 3-[4-(1-amino-cyclobutyl)-phenyl]-6-fluoro-2-phenyl-chromen-4-one, {1-[4-(6-bromo-7-methoxy-4-oxo-2-phenyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester was reacted to give the title compound as a white solid (27 mg, 76%). 1H NMR (400 MHz, DMSO-d6): δ 8.19 (s, 1H), 7.46 (s, 1H), 7.44-7.31 (m, 7H), 7.14-7.10 (m, 2H), 4.02 (s, 3H), 2.40-2.32 (m, 2H), 2.12-2.04 (m, 2H), 2.04-1.94 (m, 1H), 1.69-1.60 (m, 1H). LCMS (Method E): RT=3.87 min, [M+H]+=476/478.
