Chlorproethazine, sold under the brand name Neuriplege, is a drug of the phenothiazine group described as a muscle relaxant or tranquilizer which is or has been marketed in Europe as a topical cream for the treatment of muscle pain.[1][2][3][4][5] It has been associated with photoallergic contact dermatitis.[6][7]

Chemistry[edit]

Synthesis[edit]

Chlorproethazine can be synthesized from a diphenylsulfide derivative. The general scheme is sufficiently flexible to permit the interchange of the order of some of the steps.

Thus alkylation of aniline thioether () with 3-chloro-1-diethylaminopropane leads to the intermediate (). Ring closure as above by nucleophilic aromatic displacement leads to the antipsychotic drug chlorproethazine.[8]
