Participants

Reaction Conditions

Reaction Steps

A mixture of (E)-4-chloro-6-(4-chlorostyryl)pyrimidine Part A (120 mg, 0.48 mmol), DABCO (107 mg, 0.96 mmol), and potassium carbonate (660 mg, 4.78 mmol) in Dioxane (0.4 mL) and Water (4 mL) was stirred at 60° C. overnight. The reaction was cooled to RT, acidified with 10% HCl, extracted with EtOAC, dried (Na2SO4), and concentrated. The product was triturated with DCM to afford the desired product (E)-6-(4-chlorostyryl)pyrimidin-4(3H)-one 20B (108 mg, 0.46 mmol, 97% yield) as a light yellow solid.
