The palladium-catalyzeddirectarylation at C2 or C5 of free NH2 substituted thiophene derivatives was found to proceed in moderate to high yields using a variety of aryl halides. The choice of potassium acetate as the base was found to be crucial to inhibit the amination reaction and to promote the directarylation.

Disclosed are thienopyrimidinone derivatives as antagonists that act on metabotropic glutamate receptor subtype 1. The thienopyrimidinone derivatives show pharmacological activity against metabotropic glutamate receptor-related diseases, including pain, such as neuropathic pain and migraine, psychiatric diseases, such as anxiety disorder and schizophrenia, urinary incontinence, and neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease. Also disclosed are methods for preparing the thienopyrimidinone derivatives, and pharmaceutical compositions containing the thienopyrimidinone derivatives as active ingredients.
