Abstract
A very facile method for the synthesis of 2-arylimino-2,3-dihydropyrido[3,2-e]-1,3-thiazin-4-ones has been developed. Thus, secondary 2-chloropyridine-3-carboxamides undergo addition to aromatic isothiocyanates in the presence of sodium hydride, followed by attack of the sulfur atom of the resulting adducts on the 2-position of the pyridine ring, to give the desired products in fair to good yields.
