NEW PROCESS FOR THE PREPARATION OF 2-CYCLOPENTYL-6-METHOXY-ISONICOTINIC ACID

摘要

The present invention relates to new processes for the preparation of 2-cyclopentyl-6-methoxy-isonicotinic acid, which is a useful intermediate for the synthesis of pyridine-4-yl derivatives as immunomodulating agent. Moreover, the present invention also relates to new intermediates used in those processes.
