—; or a pharmaceutically acceptable salt or an in vivo hydrolysable ester thereof; (with provisos); possess glycogen phosphorylase inhibitory activity and accordingly have value in the treatment of disease states associated with increased glycogen phosphorylase activity. Processes for the manufacture of said heterocyclic amide derivatives and pharmaceutical compositions containing them are described.

Amino acid-mediated Goldberg reactions between amides and aryl iodides
A highly general, experimentally simple, and inexpensive catalyst system was developed for the amidation of aryl iodides by using 5 mol% of CuI as catalyst, 20 mol% of an amino acid as ligand, and K3PO4 as base. (C) 2004 Elsevier Ltd. All rights reserved.
