실험 절차

2.0 g of methyl 2-[(4,6-dimethoxypyrimidin-2-yl)oxy]-6-hydroxyiminomethylbenzoate, 3 ml of ethyl 2-bromopropionate and 0.9 g of silver oxide (I) were place in a 50 ml eggplant type flask, and were allowed to stand for one night at room temperature. 10 ml of acetone and 10 g of silica gel were added to the resultant reaction liquor, and the acetone was distilled off under reduced pressure. The resultant product was purified by column chromatography to obtain 0.7 g of the aimed compound (refractive index=1.5261) at a yield of 27%.
