Procedure

To a stirred and cooled solution of 4 parts of trans-4-amino-3-hydroxy-N,N,γ-trimethyl-α,αdiphenyl-1-piperidinebutanamide in 120 parts of trichloromethane were added 1.26 parts of N,N-diethylethanamine. A solution of 2.3 parts of 3-(trifluoromethyl)benzoyl chloride in 75 parts of trichloromethane was added dropwise. Upon completion, the reaction mixture was stirred overnight at room temperature. A solution of sodium carbonate in water was added. The separated organic layer was washed with water, dried, filtered and evaporated. The residue was taken up in 2,2'-oxybispropane. The precipitated product was filtered off and dried in vacuo at 60° C., yielding 4.9 parts (86.3%) of trans-3-hydroxy-N,N,γ-trimethyl-α,α-diphenyl-4-[[3-(trifluoromethyl)benzoyl]amino]-1-piperidinebutanamide; mp. 140.7° C. (compound 1).
