Procedure

Following General Procedure B and using 8-[(cyclopropyl-methyl-amino)-methyl]-6-ethynyl-2,2,4,4-tetramethyl-chroman (Intermediate 11, 0.09 g, 0.3 mmol), 4-iodo phenyl acetic acid methyl ester (U.S. Pat. No. 6,252,090, 0.092 g, 0.33 mmol), triethyl amine (3 mL), copper(I)iodide (0.029 g, 0.15 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.064 g, 0.09 mmol) followed by flash column chromatography over silica gel (230-400 mesh), the title compound was obtained as a yellow oil (0.085 g, 65%).
