| titleOfInvention | Process for the preparation of N-carboxymethylanthranilic acid esters |
| abstract | Process for the preparation of N-carboxymethylene anthranilic acid esters of the formula (3) by using a compound of formula (1) in which R 'represents hydrogen or a straight-chain or branched alkyl radical having 1 to 4 carbon atoms, R 1 , R 2 , R 3 , R 4 are identical or different and are independently hydrogen, halogen, NO 2 , a straight-chain or branched alkyl , Alkoxy or halogenated alkyl radical each having 1 to 6 carbon atoms, with a glyoxylic acid ester of the formula (2) OHC COOR (2) in which R represents an unsubstituted or a straight-chain or branched alkyl radical having 1 to 20 carbon atoms, phenyl radical or benzyl radical which is mono- or polysubstituted by halogen, an alkyl or alkoxy group each having 1 to 4 carbon atoms, in the presence of a Reacts solvent at 0 to 200 ° C, optionally separates the water formed in the reaction and the reaction product with hydrogen in the presence of a hydrogenation catalyst at a temperature of 0 to 200 ° C and a pressure of 1 to 150 bar. |
