実験手順

The mixture of 3-(2,3-Dihydro-benzo[1,4]dioxine-6-carbonyl)-1H-quinolin-4-one 70 mg (0.228 mmol) in DMF (1 mL) and sodium hydride 11.8 mg (0.296 mmol ) was stirred at room temperature for 60 min, followed by the addition of N-[1-(2-Bromo-1-methyl-ethylideneamino)-vinyl]-2,2,2-trifluoro-acetamide 83.8 mg (0.296 mmol). The mixture was stirred for 60 min, quenched with water, taken up with ethyl acetate, dried over sodium sulfate and purified with flash chromatography. The purified product was treated with Diethylamine in methanol over weekend, filtered to give the desired product 10 mg. LCMS observed for (M+H)+: 414.
