According to the process as shown in the following scheme having a step for reacting Compound (I) with Compound (II) to produce Compound (III), benzylpiperidine compounds useful as synthesis starting materials of pharmaceutical agents, agricultural chemicals and the like can be produced conveniently by a short step:
wherein R1 is a hydrogen atom or an amino-protecting group, R2 is a hydrogen atom, a hydrocarbon group optionally having substituents, an alkoxy group optionally having substituents or a heterocyclic group optionally having substituents, and R3 is a lower alkyl group.
根据下图所示的工艺,其中有一个步骤是使化合物 (I) 与化合物 (II) 反应生成化合物 (III),根据该工艺,可以通过一个简短的步骤方便地生产出苄基
哌啶化合物,该化合物可用作药剂、农药等的合成起始原料:
其中,R1 是氢原子或
氨基保护基,R2 是氢原子、可选带取代基的烃基、可选带取代基的烷氧基或可选 带取代基的杂环基,R3 是低级烷基。
