| titleOfInvention | METHOD FOR PRODUCING ALKYL 2-ALCOXYMETYLENE-4,4-DIFFOR-3-OXOBUTIRATES |
| abstract | Method for preparing alkyl 2-alkoxymethylene-4,4-difluoro-3-oxobutyrates (VI) where R is methyl or ethyl, from crude reaction mixtures of alkyl 4,4-difluoroacetoacetates (I) by a) interaction, where M is sodium ion or potassium, and without an additional solvent to obtain the enolate (V) b) liberating the corresponding alkyl 4,4-difluoroacetoacetate (I) from the enolate (V) using an acid, c) removing the formed salt from the cation M and the acid anion in the form of a solid, and d ) conversion of (I), without isolation from the crude reaction mixture, to alkyl 2-alkoxymethylene-4,4-difluoro-3-oxobutyrate (VI), and the use of (VI) to obtain 1-methyl-3-difluoromethylpyrazol-3-ylcarboxyates (Vii) |
