Methyl iodide → HCID 2835646, compound

Participants

Reaction Steps

To a stirred solution of 210 mg (0.87 mmol) 6-amino-4-furan-2-yl-2-thioxo-1,2-dihydro-pyridine-3,5-dicarbonitrile in 25 ml methanol were added 0.16 ml (0.87 mmol) sodium methylate solutiuon (5.4M in methanol) and 0.11 ml (1.73 mmol) methyl iodide and stirring continued for 90 minutes at room temperature. The reaction mixture was then poured onto 100 ml ice-water and the resulting crystals collected by filtration and dried in vacuo to afford 135 mg (61%) 2-amino-4-furan-2-yl-6-methylsulfanyl-pyridine-3,5-dicarbonitrile as a light brown crystalline solid. EI-MS m/e (%): 256 (M+, 49), 255 ([M—H]+, 100).
