Procedure
A mixture of 7 parts of 3-(aminocarbonyl)-4-[5,5-bis(4-fluorophenyl)pentyl]-N-(2,6-dichloro-4-nitrophenyl)-1-piperazineacetamide, 1 part of a solution of thiophene in methanol 4% and 120 parts of methanol was hydrogenated in a Parr apparatus and at 50° C. with 2 parts of platinum-on-charcoal catalyst 5%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was converted into the hydrochloride salt in 2-propanol and acetonitrile. The salt was filtered off and dried, yielding 5.55 parts (77.7%) of 3-(aminocarbonyl)-N-(4-amino-2,6-dichlorophenyl)-4-[5,5-bis(4-fluorophenyl)pentyl]-1-piperazineacetamide trihydrochloride; mp. 190.8° C. (compound 84).
