==Synthesis== class=skin-invert-image|thumb|center|500px|Synthesis of butaperazine Butaperazine can be synthesized starting from 2-butyrylphenothiazine (1). It is prepared in a manner that is comparable to the method used in the synthesis of propiomazine and propiopromazine. The phenothiazine is alkylated with 1-(γ-chloropropyl)-4-methylpiperazine (2), which is prepared in the conventional way by alkylating 1-methylpiperazine with 1-bromo-3-chloropropane.
