- A PROCESS FOR THE SYNTHESIS ANTHRANILIC DIAMIDE COMPOUNDS AND INTERMEDIATES THEREOF
-
The present invention disclosed a process for the synthesis of anthranilic diamide compound of formula (I), wherein, R1, R2, R3a, R3b, R3c, R4, R5, R6 and Z are as defined in the detailed description. The process comprising the step of obtaining a mono- or dicyano substituted aniline compound of formula (IV) which is then converted to an anthranilic acid compound of formula (V) or an anthranilic amide compound of formula (Va). Further, the compound of formula (VI) can be optionally synthesized from compound of formula (IV or V or Va).

- Potent mGluR5 antagonists: Pyridyl and thiazolyl-ethynyl-3,5-disubstituted- phenyl series
-
We report the synthesis of four series of 3,5-disubstituted-phenyl ligands targeting the metabotropic glutamate receptor subtype 5: (2-methylthiazol-4-yl) ethynyl (1a-j,), (6-methylpyridin-2-yl)ethynyl (2a-j), (5-methylpyridin-2-yl) ethynyl (3a-j,), and (pyridin-2-yl)ethynyl (4a-j,). The compounds were evaluated for antagonism of glutamate-mediated mobilization of internal calcium in an mGluR5 in vitro assay. All compounds were found to be full antagonists and exhibited low nanomolar to subnanomolar activity.
