Reaction Steps

A mixture of 10 parts of N-(3-chloropropyl)-2-nitro-4-(trifluoromethyl)benzenamine, 8.11 parts of 1-(diphenylmethyl)piperazine, 8.37 parts of sodium carbonate, 0.1 parts of potassium iodide and 200 parts of 4-methyl-2-pentanone is stirred and refluxed overnight. The reaction mixture is cooled and water is added. The organic phase is separated, washed with water, dried, filtered and evaporated. The oily residue is crystallized from 2-propanol. The product is filtered off and dried, yielding 4-(diphenylmethyl)-N-[2-nitro-4-(trifluoromethyl)phenyl]-1-piperazinepropanamine; mp. 113.7° C.
