Isopropanol → HCID 22258959, compound

Participants

Reaction Steps

To a suspension of cyanoacetamide (1.27 g, 15.1 mmol) in 2-propanol (50 mL) was added sodium hydride (60% suspension, 0.605 g, 15.1 mmol). The mixture was stirred at room temperature for 10 min. To this mixture, 1-[2-(benzyl)phenyl]-3,3-bis(methylthio)-2-propene-1-one (5.00 g, 15.1 mmol) was added in one portion. The resulting mixture was refluxed for 4 hrs. After being cooled to room temperature, the mixture was diluted with 1N HCl. The resulting precipitates were collected by filtration and washed with EtOH to give 6-[2-(benzyloxy)phenyl]-4-(methylthio)-2-oxo-1,2-dihydro-nicotinonitrile as a yellow crystalline solid (4.43 g, yield; 84%).
