Dimethylformamide → Methyl 3-(4,6-dimethoxypyrimidin-2-yl)oxy-6-phenylpicolinate

Participants

Reaction Steps

1.0 g (4.4 mmol) of methyl 6-phenyl-3-hydroxypicolinate, 0.8 g (4 mmol) of 4,6-dimethoxy-2-methylsulfonylpyrimidine and 0.6 g (4 mmol) of potassium carbonate were added to 20 ml of DMF, and were reacted at 80° C. for 0.5 hour. After the reaction, the reaction content was poured into water, and was extracted with ethyl acetate. The organic layer thus obtained was washed with water and a saturated salt water, dried and treated with an appropriate amount of Florisil. Ethyl acetate was then distilled off under reduced pressure, and the residue was crystallized by adding 20 ml of hexane thereto and allowing to stand for 3 days. The crystal thus obtained was washed with hexane/isopropyl ether to obtain an aimed compound.
