发明名称 PROCESS FOR THE RACEMIZATION OF OPTICALLY ACTIVE 1-ARYL-ALKYLAMINES
摘要 A new process for the racemization of optically active 1-aryl-alkylamines of the formula (I) <IMAGE> (I) in which Ar represents optionally substituted aryl and R represents alkyl, which is characterized in that compounds of the formula (I) which largely have the R- or S-configuration at the carbon atom marked by * are reacted with metal alkoxides in dimethyl sulphoxide, optionally in the presence of appropriate alcohols, at temperatures between 0 DEG C. and 200 DEG C.
