Reaction Conditions

Reaction Steps

According to Scheme 7 Step 7: To a cooled solution of 14(A) (220 mg, 0.43 mmol) in DMF (2 mL) under nitrogen atmosphere was added dropwise at 0° C. sodium methoxide 2M (in methanol, 215 μL, 0.43 mmol). The mixture was stirred at 0° C. for 1 h. The reaction mixture was diluted with water (100 mL) and the aqueous layer was extracted twice with DCM (100 mL). The organic layers were combined and successively dried over MgSO4, filtered and concentrated under reduced pressure to afford a brown solid. The crude solid was purified by flash chromatography with silica gel (Merck Flashmart prepacked column 25 g C18) using water/CH3CN 6/4 as eluant to afford N-(3-(4-(4-chlorobenzyl)-6-(methoxymethyl)-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide 14(B) (16 mg, 9%) as a yellow solid.
