Synthesis of butaperazine

Butaperazine can be synthesized starting from 2-butyrylphenothiazine (1).[2] It is prepared in a manner that is comparable to the method used in the synthesis of propiomazine and propiopromazine.Script error: No such module "Unsubst". 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.
