At room temperature (RT), 53.6 mg (0.2 mmol) of 2-amino-4-(4-hydroxyphenyl)-6-sulfanyl-3,5-pyridinedicarbonitrile and 45.6 mg (0.3 mmol) of N-methylbromoacetamide are stirred in 0.5 ml of dimethylformamide (DMF) together with 33.6 mg (0.4 mmol) of NaHCO3 for 4 hours. Thin-layer chromatography (TLC) (CH2Cl2/CH3OH 10:1) shows complete conversion. The entire mixture is diluted with water and ethyl acetate (EA) and the EA phase is dried with MgSO4 and concentrated under reduced pressure. The residue crystallizes from methanol.
