【発明の名称】α―(3―ベンゾイルフェニル)プロピオン酸誘導体の製造方法
Document Type and Number:
Japanese Patent JP2782080
Kind Code:
B2
Abstract:
This invention provides a method of producing highly pure alpha -(3-benzoylphenyl)propionic acid derivatives, which are pharmaceuticals per se or which can easily afford the same, from readily available 3-ethylbenzophenone in a very simplified manner efficiently and economically. The method comprises dehydrogenating 3-ethylbenzophenone in vapor phase in the presence of an inert gas and carbonylating the formed 3-ethenylbenzophenone in the presence of a carbonylation catalyst comprising a transition metal complex.
