HCID 67067908(1-{4-[4-oxo-2-phenyl-8-(1H-pyrazol-4-yl)-4H-chromen-3-yl]-phenyl}-cyclobutyl)-carbamic acid tert-butyl ester수율 74%

실험 절차

Following the procedure used to prepare (1-{4-[4-oxo-2-phenyl-7-(2H-pyrazol-3-yl)-4H-chromen-3-yl]-phenyl}-cyclobutyl)-carbamic acid tert-butyl ester, {1-[4-(8-bromo-4-oxo-2-phenyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester was reacted with 4-pyrazoleboronic acid pinacol ester to give the title compound as a colourless oil (108 mg, 74%). LCMS (Method G): RT=3.86 min, [M+H]+=534.
