실험 절차
Experimental conditions analogous to those described for Step 3 of Example 1 were used with 100 mg (0.324 mmol) of 3-(4-Methoxy-3-methyl-benzoyl)-6-methyl-1H-[1,5]naphthyridin-4-one, 97.7 mg (0.389 mmol) of 2-bromo-6-bromomethyl-pyridine, 15.6 mg (0.389 mmol, 60% dispersion in oil), and 1 mL of N,N-dimethylformamide. The crude product was purified by flash column chromatography using a gradient of 20-100% ethyl acetate in hexane and further purified on the reverse phase HPLC with a C18 column, gradient of 20-70% acetonitrile—0.1% TFA to yield 52.6 mg of 1-(6-Bromo-pyridin-2-ylmethyl)-3-(4-methoxy-3-methyl-benzoyl)-6-methyl-1H-[1,5]naphthyridin-4-one. LC-MSD, m/z for C24H20BrN3O3 [M+H]: 478.07 LC retention time on HPLC, C18 column gradient 20-95% acetonitrile with 0.1% TFA in 4 minutes: 2.1 min
