Procedure

According to Scheme 6 Step 2: To a stirred solution of N-(3-(5-methoxy-3-oxo-1,2,4-triazin-2(3H)-yl)phenyl)acetamide (40 mg, 0.15 mmol) in acetonitrile (3 mL) were added 1-(bromomethyl)-4-chloro-2-fluorobenzene (52 mg, 0.23 mmol) and sodium iodide (46 mg, 0.31 mmol). The mixture was heated irradiated at 160° C. under microwave irradiation. The reaction mixture was quenched with water and extracted with ethyl acetate (×3). The combined organic layers were successively washed with water then with brine, dried over MgSO4, filtered and concentrated. The crude product was purified by flash chromatography, 5 g column, CH2Cl2/MeOH 98/2 to afford the N-(3-(4-(4-chloro-2-fluorobenzyl)-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide 10(B) as a yellow solid (13 mg, 22%).
