ABSTRACT:
The yield of compounds having the general formula: ##EQU1## wherein R represents ##STR1## in the process comprising reacting a substituted hydroxycyclohexanecarboxylic acid with an aminoisopropyl chloride, is highly improved by heating the reaction mixture to 160.degree. to 240.degree. C. for at least 3 hours, and distilling under reduced pressure the resulting product. Thus the content of the undesired isomer is reduced to less than 1-1.5%.
