Process for the preparation of substituted crotonic acid esters |
| abstract |
According to the invention there is proposed a process for the preparation of 4,4,4-trifluoro-3-methylamino-crotonic acid esters by dehydrating trifluoroacetoacetic acid esters and methylamine in the presence of an inert reaction medium and of a C 1 -C 4 carboxylic acid, in which process the reaction is carried out at a temperature of from 75 to 100° C. without isolation of intermediates and the water that forms during the reaction is removed continuously from the reaction medium. |
