Reaction Conditions

Reaction Steps

According to Scheme 2 Step 4: To a solution of 2(C) (100 mg, 0.22 mmol) in 0.5 mL of DMF was added dimethylamine 2M solution in methanol (0.56 mL, 1.11 mmol). The reaction was heated 5 h at 150° C. under microwave irradiation. The reaction mixture was quenched with water and extracted with ethyl acetate (×3). The combined organic layers were washed successively with water, with brine, dried over MgSO4, filtered and concentrated. The crude product was purified by flash chromatography, 5 g column (Eluant: DCM/MeOH 98/2). 10 mg, (11% yield) of N-(3-(4-(4-chlorobenzyl)-6-(dimethylamino)-3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)phenyl)acetamide 2(D) were obtained.
