Experimental conditions analogous to those described for Step 3 of Example 1 were used with 100 mg (0.341 mmol) of 3-(4-Methoxy-3-methyl-benzoyl)-1H-quinolin-4-one, 80.6 mg (0.409 mmol) of 6-bromomethyl-pyridine-2-carbonitrile, 16.4 mg (0.409 mmol, 60% dispersion in oil), and 3.5 mL of N,N-dimethylformamide. The crude product was purified by flash column chromatography using a gradient of 20-100% ethyl acetate in hexane to yield 58 mg of 6-[3-(4-Methoxy-3-methyl-benzoyl)-4-oxo-4H-quinolin-1-ylmethyl]-pyridine-2-carbonitrile. LC-MSD, m/z for C25H19N3O3 [M+H]: 410.14 LC retention time on HPLC, C18 column gradient 20-95% acetonitrile with 0.1% TFA in 4 minutes: 2.3 min.
