Reaction Steps

2-Cyano-N-(3-methyl-4-nitrophenyl)acetamide (0.61 g; 2.8 mmol) is dissolved in tetrahydrofuran (30 ml) and sodium hydride (80% strength dispersion in oil; 0.21 g; 7 mmol) is added. The mixture is stirred at 25° C. for 15 minutes and 1-acetylimidazole (0.46 g; 4.2 mmol) is added dropwise over the course of 5 minutes and the mixture is stirred for a further 15 minutes. 2 ml of glacial acetic acid are added and the mixture is stirred at 25° C. for 1 hour and then poured into ice-cold water (100 ml). The pH of the solution is then adjusted to 1 using concentrated hydrochloric acid, and the precipitate is filtered, washed with water and brought to dryness under reduced pressure. N-(3-Methyl-4-nitrophenyl)-2-cyano-3-hydroxycrotonamide is thus obtained.
