Procedure

Following General Procedure B and using 5-(cyclopropyl-methyl-amino)-2-ethynyl-8,8-dimethyl-4-methoxy-5,6,7,8-tetrahydro-naphthalene (Intermediate 81, 0.095 g, 0.336 mmol), methyl-4-iodocinnamate (Reagent 4, 0.097 g, 0.336 mmol), triethyl amine (8 mL), copper(I)iodide (0.019 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 5–15% ethyl acetate in hexane as the eluent, the title compound was obtained as a white solid (0.12 g, 80%).
