実験手順
Following General Procedure B and using 8-[(cyclopropyl-methyl-amino)-methyl]-6-ethynyl-2,2,4,4-tetramethyl-chroman (Intermediate 11, 0.08 g, 0.27 mmol), methyl-2-(4-iodophenyl)-2-methyl-propionate (Reagent 2, 0.082 g, 0.27 mmol), triethyl amine (2 mL), copper(I)iodide (0.020 g, 0.1 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.07 g, 0.1 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 10% ethyl acetate in hexane as the eluent, the title compound was obtained as a brown oil (0.040 g, 31%).
