| titleOfInvention | Preparation of 3-carbamoylisoxazole-4-carboxylic esters by selective amidation |
| abstract | Abstract of the Disclosure: 3-Carbamoylisoxazole-4-carboxylic esters of the formula I <IMAGE> I where R1 is hydrogen, alkyl, cycloalkyl, phenyl or a 5- to 6-membered heterocyclic radical, it being possible for the organic radicals to carry substituents which are inert under the reaction conditions; R2 is alkyl, cycloalkyl, benzyl or C1-C3-alkenyl; R3 is hydrogen, alkyl or cycloalkyl and R4 is an aliphatic or cycloaliphatic radical or unsubstituted or substituted phenyl, or R4 together with R3is a 4- to 7-membered alkylene chain which can be interrupted by oxygen, sulfur or N-methyl, are prepared by selective amidation of an isoxazole-3,4-dicarboxylic diester of the formula II <IMAGE> II where R2 has the meanings of R2 and is identical to or different from R2. |
