4-(3-METHOXY-PROPOXY)-2,3-DIMETHYLPYRIDINE-N-OXIDE SYNTHESIS METHOD |
| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to a method for synthesis of 4-(3-methoxy-propoxy)-2,3-dimethylpyridine-N-oxide from 4-chloro-2,3-dimethylpyridine-N-oxide and 3-methoxypropanol, according to which the reaction takes place in a 3-methoxypropanol medium in the presence of a hydroxide of an alkali metal at 100-120C. ^ EFFECT: simplification of the process owing to use of cheaper and safe compound - hydroxide of an alkali metal, and considerable increase in output of the product. ^ 1 cl, 4 ex |
