Experimental conditions analogous to those described for Step 6 of Example 60, from 100 mg (0.248 mmol) of 1-(6-Bromo-pyridin-2-ylmethyl)-4-oxo-1,4-dihydro-[1,8]naphthyridine-3-carboxylic acid methoxy-methyl-amide in THF 2 ml, was added 1.09 ml (0.545 mmol) 3,4-dimethoxyphenylmagnesium bromide. The reaction mixture was stirred at room temperature for 30 min, then quenched with saturated solution of NH4Cl, extracted with ethyl acetate and purified with flash chromatography to give the desired product 22 mg. LCMS observed for (M+H)+: 480.
