Procedure

A mixture of 2-cyanophenol (39.7 g), potassium carbonate (62.2 g), polyethylene glycol 400 (60.0 g), (E)-methyl 2-[2-(6-chloropyrimidin-4-yloxy)phenyl]-3-methoxypropenoate (98.3 g) and toluene (130 g) was heated at 105° C. for 16 hours. (E)-methyl 2-[2-(6-(2-cyanophenoxy)pyrimidin-4-yloxy)phenyl]-3-methoxypropenoate was produced (89.5 area %).
