To a solution of 0.060 g (0.216 mmol) of 3-(3,4-Dimethyl-benzoyl)-1H-[1,5]naphthyridin-4-one in 2.0 mL of N,N-dimethylformamide was added 10.4 mg (0.259 mmol, 60% dispersion in oil) of sodium hydride and the reaction was stirred for 5 min. 65 mg (0.259 mmol) of 2-bromo-6-bromomethyl-pyridine was added and the reaction was stirred at room temperature for 3 h. Water was added and the solid collected by filtration. The crude brown solid was purified on the reverse phase HPLC with a C18 column, gradient of 20-70% acetonitrile—0.1% TFA to yield 11.8 mg of 1-(6-Bromo-pyridin-2-ylmethyl)-3-(3,4-dimethyl-benzoyl)-1H-[1,5]naphthyridin-4-one as an off white solid.
