ABSTRACT:
The invention provides an efficient method for preparing 3-endo-(8-azabicyclo[3.2.1]oct-3-yl)benzamide by hydrogenation, under controlled conditions, of an amino-protected 3-(8-azabicyclo[3.2.1]oct-2-en-3-yl)benzamide intermediate in which the amino-protecting group is removable by catalytic hydrogenation.
