Preparation of phenylpropionic avid derivative |
| abstract |
The invention relates to the field of organic chemistry, and more specifically to the synthesis of phenylpropionic acids. Its specific subject is a new process for the preparation of 2-[4-(R-amino)phenyl]propionic acids of general formula I <IMAGE> which consists in subjecting a 2-(4-aminophenyl)propionic derivative of formula II <IMAGE> in which R1 is hydrogen or a C1-C6 alkyl radical, to the action of an alkylating agent in a heterogeneous phase in the presence of a phase transfer catalyst and a basic agent in an aqueous medium. The acids obtained are active principles of medicaments. |
