Reaction Steps

To a solution of 3-(dimethylamino)-1-(4-fluorophenyl)-2-(4-pyridyl)prop-2-en-1-one (12.77 g, 47.2 mmol, obtained in reference example 7) in DMF (175 mL), 2-cyanoacetamide (4.41 g, 52.0 mmol) was added under argon atmosphere. Then, sodium methoxide (5.35 g, 99.2 mmol) was added and heated to reflux for 1 hour. The mixture was allowed to cool, concentrated and diluted with water. The pH was adjusted to 4 with 1 N HCl.
