Process For Preparing N-(Substituted Arylmethyl) -4-Substituted-4-(Disubstituted Methyl) Piperidines And Intermediates

摘要

An improved process is described for preparing a N-(substituted arylmethyl)-4-substituted-4-(disubstituted methyl)piperidine of formula (I): wherein R¹ and R² are independently selected from the group consisting of halogen, CF₃, OCF₃, OCHF₂, OCF₂CHF₂ and SF₅; and Z and B are independently selected from the group consisting of CH and N; as well as processes for preparing intermediates useful in the overall process.
