| abstract | Process for the manufacture of derivatives of 5-methoxymethylpyridine-2,3-djcarboxylic acid. Abstract. A process for the manufacture of a 2,3-disubstituted-5-methoxymethylpyrine of the formula (I), where Z is H or halogen; Z1 is H, halogen, CN or NO2; Y2 is OM, and M is an alkali metal or an alkaline earth metal, comprising the step of: (i) reacting a compound of the formula (II) where Q is an aliphatic or cyclic, saturated, partially unsaturated or aromatic tertiary amine ; Z is H or halogen; Z1 is H, halogen, CN or NO2; Y1 and Y2 each are independently OR1, NR1R2, or when taken together Y1 Y2 is -0-, -S- or -NR3-; R1 and R2 each are independently H, C1-C4 alkyl optionally substituted with C1-C4 alkoxy or phenyl optionally substituted with one to three C1-C4 alkyl groups, C1-C4 alkoxy groups or halogen atoms, or phenyl optionally substituted with one to three C1-C4 alkyl groups, C1-C4 alkoxy groups or halogen atoms; R3 is H or C1-C4 alkyl in a methanol / mixture H20, which comprises at least 20% by weight H20 (based on the sum of water and bromine (II), with a base comprising MOCH3 and / or MOH, where M is alkali metal or alkaline earth metal, under pressure in a closed container at a temperature of from 75 to 110 ° C. The compounds of the formula (I) are useful intermediates in the synthesis of herbicidal imidazolinones, similar to imazamox. |
