Versuchsvorschrift
According to Scheme 3 Step 3: To a solution of compound 6(B) (800 mg, 2.19 mmol) in MeOH (10 mL) was added a solution of sodium methoxyde 2M in methanol (1.1 mL, 2.19 mol). After 1 h of stirring at room temperature, the mixture was quenched with water and extracted with ethyl acetate (×3). The combined organic layers were successively washed with water, brine, dried over MgSO4, filtered and concentrated under reduced pressure. The crude solid was purified by flash chromatography with silica gel (Merck Flashmart prepacked column 10 g SiO2) using CH2Cl2/MeOH 98/2 as eluant to afford N-(3-(4-allyl-6-methoxy-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide 6(C) (600 mg, 86%) as a white solid.
