Reaction Steps

To 160 mL of an ethanol solution of 13.0 g (45.1 mmol) of (E)-3-(4-bromophenyl)-1-(2-pyridyl)-2-propen-1-one, 7.3 g (46.6 mmol) of benzamidine hydrochloride and 3.6 g (90 mmol) of sodium hydroxide were added under argon atmosphere, and the mixture was stirred for 16 h under heat refluxing. After cooling the reaction mixture to room temperature, a formed solid was collected by filtration and washed with water and methanol to obtain 4.31 g (yield: 25%) of 4-(4-bromophenyl)-2-phenyl-6-(2-pyridyl)pyrimidine as a pale brown solid.
