| titleOfInvention | Process for preparing carboxamide oximes |
| abstract | The invention relates to a process for preparing carboxamide oximes of the formula (I): in which R 1 represents an aryl or heteroaromatic group, and R 2 and R 3 represent a hydrogen atom or groups as defined in the description, characterized by the three following steps: n 1) An amide of the formula (II) R 1 CONHR 4 , with R 1 having the previous meaning and R 4 being a C 1 to C 8 alkyl group, is reacted with a chlorinating agent in order to obtain the corresponding chloroimine, n 2) The resulting chloroimine is then caused to react with an aminopyrazole in order to obtain a novel disubstituted amidine, n 3) The resulting amidine is caused to react with hydroxylamine or one of its salts. n Carboxamide oximes are prepared more rapidly, and in a good yield, in this way. They are useful as synthesis intermediates, in particular for preparing photographic developing agents. |
