Title:
How to prepare a Aryl acetic acid derivative and a heteroaryl acetic acid derivative
Document Type and Number:
Japanese Patent JP6100174
Kind Code:
B2
Abstract:
The invention relates to a process for preparing aryl- and heteroarylacetic acids and derivatives thereof by reaction of aryl or heteroaryl halides with malonic diesters in the presence of a palladium catalyst, of one or more bases and optionally of a phase transfer catalyst. This process enables the preparation of a multitude of functionalized aryl- and heteroarylacetic acids and derivatives thereof, especially also the preparation of arylacetic acids with sterically demanding substituents.
