Reaction Steps

Potassium hexamethyldisilazane (2.44 mL, 1.22 mmol, 0.5 M in THF) was added to a solution of 3-(4-Methoxy-3-methyl-benzoyl)-1H-quinolin-4-one (0.30 g, 1.02) in 10 mL of tetrahydrofuran. After the reaction was stirred at rt for 20 minutes, N-(6-Bromomethyl-pyridin-2-yl)-2,2,2-trifluoro-acetamide (0.35 g, 0.246 mmol) was added and stirred overnight at room temperature. Water and ethyl acetate were added and the two phases were separated. The aqueous phase was extracted with ethyl acetate (3×20 mL). The combined organic layers were dried with magnesium sulfate, filtered and concentrated in vacuo. The crude brown solid was purified by reverse phase HPLC with a C18 column, gradient of 20-70% acetonitrile—0.1% TFA to yield 212 mg of 2,2,2-Trifluoro-N-{6-[3-(4-methoxy-3-methyl-benzoyl)-4-oxo-4H-quinolin-1-ylmethyl]-pyridin-2-yl}-acetamide
