Methanol → methyl 2-[(4,6-dimethoxytriazin-2-y1)oxy]-6-[1-(N-methoxyimino)ethyl]benzoate

참여 물질

반응 단계

0.9 of methyl 2-acetyl-6-[(4,6-dimethoxytriazin-2-yl)oxy]benzoate, 0.68 g of methoxyamine hydrochloride and 0.80 g of potassium acetate were added to 30 ml of methanol, and the resultant mixture was stirred for one day and one night at room temperature. The resultant reaction liquor was poured into water, and was extracted with ethyl acetate. After washing the extracted product with water, the washed product was dried and concentrated to obtain an oily product. This was then purified by column chromatography to obtain 0.47 g of the aimed compound (melting point=131° to 135° C.) at a yield of 48%.
