How is 1-[1-(3-Methoxy-4-nitrophenyl)-4-piperidinyl]-4-methylpiperazine (CAS: 761440-65-7) typically synthesized?

1-[1-(3-Methoxy-4-nitrophenyl)-4-piperidinyl]-4-methylpiperazine (CAS: 761440-65-7) is synthesized through a multi-step process. The key steps include the synthesis of the 3-methoxy-4-nitrophenyl piperidine, followed by the formation of the 4-methylpiperazine derivative. This is typically achieved using standard organic synthesis techniques, such as nucleophilic substitution and condensation reactions. The yield is around 75-85%, and the selectivity is high.
