Procedures were developed for the synthesis of 3-methyl-5-phenylethynyl[1, 2,4]triazine (4), 6-methyl-3-phenylethynyl[1,2,4]triazine (5), and 5-methyl-3-phenylethynyl[1,2,4]triazine (6a) as analogues of 2-methyl-6-(phenylethynyl)pyridine (2). The compounds were evaluated for antagonism of glutamate-mediated mobilization of internal calcium in an mGluR5 in vitro efficacy assay. The most potent of the three analogues was 6a. Twenty additional analogues of 6a were synthesized and evaluated for mGluR5 antagonist efficacy. The most potent compounds were 3-(3-methylphenylethynyl)-5-methyl[1,2, 4]triazine (6b), 5-(3-chlorophenylethynyl)-5-methyl[1,2,4]triazine (6c), and 3-(3-bromophenylethynyl)-5-methyl[1,2,4]triazine (6d).

An unprecedented catalytic aza-Michael addition to substituted 3-vinyl-1,2,4-triazines, as original bifunctional platforms for the domino conjugate addition inverse-electron-demand hetero-Diels-Alder/retro-Diels-Alder (ihDA/rDA) reaction, was achieved using the highly acidic triflimide as an organocatalyst. Based on the use of alkoxyamine nucleophiles, this sequence not only highlights a rare example of the catalytic aza-Michael reaction to alkenylazaarenes but also proves to be useful for the elaboration of an array of biorelevant tetrahydro-[1,6]-naphthyridines.
