Process for the preparation of basic esters of substituted hydroxycyclohexanecarboxylic acids |
abstract |
ABSTRACT OF THE DISCLOSURE The yield of compounds having the general formula: (I) wherein R represents . or in the process comprising reacting a substituted hydroxy-cyclohexanecarboxylic acid with an aminoisopropyl chloride is highly improved by heating the reaction mixture to 160 to 240°C for at least 3 hours, and distilling the resulting product under reduced pressure. This process enables the content of the undesired isomer to be reduced to less than 1-1.5%. |
