Procedure
To a stirred solution of 0.19 g (0.75 mmol) 6-amino-4-phenyl-2-thioxo-1,2-dihydro-pyridine-3,5-dicarbonitrile in 25 ml methanol were added 0.14 ml (0.76 mmol) sodium methylate solutiuon (5.4M in methanol) and 0.09 ml (1.5 mmol) methyl iodide and stirring continued for 16 hours at room temperature. The reaction mixture was then cooled to 0° C. and the resulting crystals collected by filtration and washed with ether/methanol (3/1) to afford 0.1 g (50%) 2-amino-6-methylsulfanyl-4-phenyl-pyridine-3,5-dicarbonitrile as a white crystalline solid. EI-MS m/e (%): 266 (M+, 40), 265 ([M—H]+, 100).
