Versuchsvorschrift

In a manner analogous to that described in Example 2, 1-(4-nitro-3-bromobenzoyl)-4-[2-(4-chlorophenyl)ethyl]-piperazine is prepared from 4.7 g of 4-nitro-3-bromobenzoic acid and 1-[2-(4-chlorophenyl)ethyl]-piperazine and, as described in Example 3, reduced in the presence of Raney nickel to form 1-(4-amino-3-bromobenzoyl)-4-[2-(4-chlorophenyl)ethyl]-piperazine having a melting point of 120°-123°.
