The reaction was performed with tert-butyl iodide 1a (0.1 mmol, 1.0 equiv), phenyl vinyl ether 2a (0.4 mmol, 4 equiv.) and 3-methoxyphenyl Grignard 3a (0.15 mmol, 1.5 equiv.). Aryl Grignard 3a was added dropwise via syringe pump over 1 h. The yield was determined by 1H NMR using dibromomethane as internal standard.
