Procedure

Following General Procedure B and using 5-(cyclopropyl-methyl-amino)-2-ethynyl-8,8-dimethyl-methoxy-5,6,7,8-tetrahydro-naphthalene (Intermediate 81, 0.065 g, 0.23 mmol), methyl-4-iodophenylacetate (0.063 g, 0.23 mmol), triethyl amine (8 mL), copper(I)iodide (0.018 g, 0.093 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.065 g, 0.093 mmol) followed by flash column chromatography over silica gel (230–400 mesh) using 5–20% ethyl acetate in hexane as the eluent, the title compound was obtained as a yellow solid (0.09 g, 90%).
