Procedure

A solution of 3 parts of 3-(aminocarbonyl)-4-[4,4-bis(4-fluorophenyl)butyl]-N-(2,6-dimethylphenyl)-1-piperazineacetamide in 80 parts of 2-propanone was added to a solution of 1.9 parts of (Z)-2-butenedioate in 40 parts of 2-propanone: slowly crystallization. The product was filtered off and recrystallized twice from 2-propanol and once from 2-propanone, yielding 1.56 parts (39%) of 3-(aminocarbonyl)-4-[4,4-bis(4-fluorophenyl)butyl]-N-(2,6-dimethylphenyl)-1-piperazineacetamide (Z)-2-butenedioate (1:2) monohydrate; mp. 119.6° C. (compound 174).
