3-[4-(1-Amino-cyclobutyl)-phenyl]-6-fluoro-2-phenyl-chromen-4-one → 3-[4-(1-Amino-cyclobutyl)-phenyl]-7-methoxy-4-oxo-2-phenyl-4H-chromene-6-carbonitrile

Participants

Reaction Steps

Following the procedure used to prepare 3-[4-(1-amino-cyclobutyl)-phenyl]-6-fluoro-2-phenyl-chromen-4-one, {1-[4-(6-cyano-7-methoxy-4-oxo-2-phenyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester (81 mg, 0.155 mmol) was reacted to give the title compound (39 mg, 60%). LCMS (Method E): RT=3.57 min, [M+H]+=423. 1H NMR (400 MHz, DMSO-d6): δ 8.36 (s, 1H), 7.53 (s, 1H), 7.41-7.26 (m, 7H), 7.09 (d, J=8.1 Hz, 2H), 4.01 (s, 3H), 2.85 (bs, 2H), 2.37-2.27 (m, 2H), 2.10-1.88 (m, 3H), 1.66-1.54 (m, 1H).
