A novel synthesis of the antipsychotic agent ziprasidone

A new synthesis of the antipsychotic ziprasidone from 2,5-dichloro-4-nitrotoluene 3 is presented. The nitro group in 3 was used to activate the orthochlorine for displacement and the methyl group for enamine formation and introduction of the piperazinyl moiety.

Processes and intermediates for the preparation of 5-[2-(4-(benzoisothiazol-3-yl)-piperazin-1-yl)ethyl]-6-chloro-1,3-dihydro-indol-2-one

A process for preparing the compound of the formula STR1 which comprises treating a compound of the formula STR2 wherein R2 is hydrogen, CN or CO2 R1 and R1 is hydrogen or (C1 -C6)alkyl with a reducing agent with the proviso that when R2 is CN or CO2 R1 and R1 is (C1 -C6)alkyl the product of the reduction is heated with an acid. Compounds of formula II wherein R2 is CN or CO2 R1 and R1 is (C1 -C6)alkyl or R2 is hydrogen and R1 is (C1 -C6)alkyl or hydrogen. The compound of formula VII R1 is (C1 -C6)alkyl. The compound of formula III. The compound of formula I is useful in the treatment of psychotic disorders.
