Novel aminoketones useful as central muscle relaxants and their preparation processes are disclosed. The disclosed processes are novel processes which do not use any heavy metal in view of the facts that their products are will be used as drugs and which require no complex purification step such as liberation of the aminoketones from their hydrochlorides or the like.

Aminoketone derivative compounds containing a heterocyclic ring bonded to an aminoketone moiety and useful as effective ingredients of centrally acting muscle relaxants and pollakiurea curing agents. (+)3-phenyl-5-[2-(1-pyrrolidinylmethyl)butyryl]isoxazole, which has a more remarkable central muscle relaxant action as compared with its racemic modification, can be effectively separated from the racemic modification using optically active 10-camphorsulfonic acid as the agent for the optical resolution.
