Reaction Steps

According to Scheme 5 Step 5: A suspension of N-(3-(3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide (50 mg, 0.203 mmol), 4-cyanobenzylbromide (40 mg, 0.203 mmol) and potassium carbonate (31 mg, 0.223 mmol) in acetonitrile (2 mL) was stirred at 60° C. for 15 h The reaction mixture was then partitioned between AcOEt and water The organic layer was washed twice with water and once with brine. The organic layer was dried over MgSO4 and evaporated under reduced pressure. The crude product was purified by flash chromatography over silica gel (Merck Flashmart prepacked column 10 g SiO2) using DCM/MeOH 98/2 as eluent to afford N-(3-(4-(4-cyanobenzyl)-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide 9(E) (26 mg, 35%) as a white solid.
