2-(Bromomethyl)-6-(trifluoromethyl)pyridine → 3-(4-Methoxy-3-methyl-benzoyl)-1-(6-trifluoromethyl-pyridin-2-ylmethyl)-1H-quinolin-4-one

Participants

Reaction Steps

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, 98.2 mg (0.409 mmol) of 2-bromomethyl-6-trifluoromethyl-pyridine, 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 39 mg of 3-(4-Methoxy-3-methyl-benzoyl)-1-(6-trifluoromethyl-pyridin-2-ylmethyl)-1H-quinolin-4-one. LC-MSD, m/z for C25H19F3N2O3 [M+H]: 453.13 LC retention time on HPLC, C18 column gradient 20-95% acetonitrile with 0.1% TFA in 4 minutes: 2.5 min.
