Procedure

To a suspension of 2-oxo-1,2-dihydropyridine-3-carbonitrile (0.211 g) in methanol (14 mL) was added a 40% aqueous solution of ammonium sulfide (0.50 mL). The reaction mixture was heated at 130° C. in a microwave reactor for 2 hours. The reaction mixture was concentrated. The residue obtained was triturated with methanol and the solid filtered to obtain the title compound (0.174 g) having the following physical data.
