Reaction Steps
The reaction of tert-butyl N-(3-bromopropyl)carbamate and N-[3-(1,2,3,6-tetrahydro-4-pyridinyl)phenyl]acetamide in refluxing dioxane with catalytic Bu4NI and base as described in Scheme A gave tert-butyl 3-(4-[3-(acetylamino)phenyl]-3,6-dihydro-1(2H)-pyridinyl)propylcarbamate. Deprotection of the BOC group using HCl in dioxane followed by basification (pH 11–12) gave the desired product.
