Reaction Steps

According to Scheme 4 Step 2: A mixture of compound 8(A) (100 mg, 0.39 mmol), 3-acetamidophenylboronic acid (107 mg, 0.59 mmol), copper acetate (79 mg, 0.44 mmol) and pyridine (65 μl, 0.79 mmol) in DMF (3 mL) was stirred at 65° C. during 15 hours. The reaction mixture was diluted with 100 mL of a saturated solution of NaHCO3 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 reduce pressure to afford a brown solid. The crude solid was purified by flash chromatography with silica gel (Merck Flashmart prepacked column 20 g, C18) using Water/CH3CN 6/4 as eluant to afford N-(3-(4-(4-chlorobenzyl)-6-methyl-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide 8(B) (97 mg, 63%) as a white solid.
