According to Scheme 2 Step 4: To a stirred solution of 3-(4-(4-chlorobenzyl)-6-bromo-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)benzonitrile (0.300 g, 0.72 mmol) in DMF (5 ml) was added, dropwise, at 0° C., 2M solution of sodium methoxide (0.72 mmol, 0.359 ml). The mixture was stirred 1 hour at 0° C. then 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, 10 g prepacked column, DCM 100%. 150 mg (Yield=57%) of 3-(4-(4-chlorobenzyl)-6-methoxy-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)benzonitrile were recovered and used for the next step.
