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.
该发明提供了一种高效的方法,通过在受控条件下对
氨基保护的3-(8-azabicyclo[3.2.1]oct-2-en-3-yl)苯甲酰胺中间体进行氢化,制备3-内环-(8-azabicyclo[3.2.1]oct-3-yl)苯甲酰胺,其中
氨基保护基可通过催化氢化去除。
