Diisopropylamine → methyl (E)-[2-methyl-4-[3-[4-[3-(morpholin-4-yl)propynyl]phenyl]-3-(4-trifluoromethylphenyl)allyloxy]phenoxy]acetate

Participants

Reaction Steps

4-Propargylmorpholine (193 mg, 1.55 mmol) and diisopropylamine (0.51 mL, 3.64 mmol) were added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-(4-trifluoromethylphenyl)-allyloxy]-2-methylphenoxy]acetate (450 mg, 0.773 mmol; example 4) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (12 mg, 0.063 mmol) and bis(triphenylphosphine)palladium(II) dichloride (27 mg, 0.039 mmol) were added. The reaction mixture was stirred at ambient temperature for 19 h and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane/methanol 99:1) yielding methyl (E)-[2-methyl-4-[3-[4-[3-(morpholin-4-yl)propynyl]-phenyl]-3-(4-trifluoromethylphenyl)allyloxy]phenoxy]acetate as brown oil.
