| titleOfInvention | Method of synthesis of 3-quinolonecarboxylic acid derivatives |
| abstract | The object of the invention is a method for producing 3-quinolone carboxylic acid derivatives of the general formula 1 given in the description, which consists in reacting an acid halide of the formula 2 with an aminocrylic acid ester of the general formula 3RNH-CH = CH -COOR or first with a dimethylaminoacrylic ester acids of the general formula 4 (CH) N-CH = CH-COOR and then with the amine of the formula (5) R-NH obtained in this compound of the general formula (6) are subjected to cyclization in the presence of an alkaline agent, followed by interaction the compounds of general formula (7) with a heterocyclic compound of general formula (8) and alkaline saponification of the resulting compound of formula (9), each stage being carried out without preliminary isolation of the corresponding intermediate products, and the target product is isolated in free form or in the form salt. Formulas 1,2,6,7,8 and 9 are given in the description. The radicals A, R-R, X-X and Hal shown in formulas 1-9 have the meanings indicated in the description. |
