Procedure

Experimental conditions analogous to those described for Step 3 of Example 1, from 50 mg (0.17 mmol) of 3-(4-Methoxy-3-methyl-benzoyl)-1H-[1,8]naphthyridin-4-one in THF 2 ml, was added KHMDS in THF 0.4 ml (0.2 mmol ) slowly. The reaction mixture was stirred at room temperature for 60 min, followed by the addition of 40 mg (0.2 mmol) of 6-Bromomethyl-pyridine-2-carbonitrile. The mixture was heated to 60° C. for 60 min, then quenched with water and purified with HPLC to give the desired product (15 mg). LCMS (M+H)+: 411.1.
