PROCESS FOR PRODUCING OPTICALLY ACTIVE N-ALKYL-PIPERIDINE-2-CARBOXANILIDE
摘要
<p>Disclosed herein is a process for producing optically active 1-n-propyl-2',6'-dimethyl-2-piperidinecarboxanilide. The process comprises of reacting n-propyl pipecolate ester with 2,6-dimethylanilino magnesium halide. The 1-n-propyl-2',6'-dimethyl-2-piperidinecarboxanilide obtained according to the process is having chiral purity of more than 97%.</p>
