The present invention is directed to a process for the preparation of aryl-carbonyl-pyrrolidine carboxylic acid derivative compounds which are useful in treating metabolic diseases, said process consisting of coupling a pyrrolidine ester compound with an aryl carboxylic acid derivative, followed by alkaline or acidic treatment, hydrogenolysis or treatment with a fluoride of the obtained intermediate, to afford novel aryl-carbonyl-pyrrolidine carboxylic acid derivative compounds. |
