실험 절차

A solution of 4-phenyl-7-trifluoromethanesulfonyloxycoumarin (1.75 g) and tetrakis (triphenylphosphine)palladium (0) (600 mg) in Et3N (1.3 mL), MeOH (15 mL) and DMSO (25 mL) was stirred under an atmosphere of carbon monoxide for 1 hr. at 70° C. The mixture was then poured onto sat. NH4Cl solution, extracted with EtOAc, dried and evaporated. Chromatography on silica gel (30% EtOAc/hexane) yielded the title compound as a solid, m.p. 133°-135° C.
