실험 절차

Following General Procedure D and using trifluoro-methanesulfonic acid 5-tert-butyl-2-methyl-phenyl ester (Intermediate 108, 0.28 g, 0.94 mmol), triethyl amine (3 mL), trimethylsilyl acetylene (1 mL, 7 mmol), N,N-dimethylformamide (6 mL) and dichlorobis(triphenylphosphine)palladium(11) (0.053 g, 0.076 mmol) followed by flash column chromatography over silica gel (230–400 mesh) using hexane as the eluent, the title compound (0.16 g, 69%) was obtained.
