Reaction Steps

To 250 mg of 6-fluoro-4-(4-phenoxy-phenylamino)-[1,7]naphthyridine-3-carbonitrile under an inert atmosphere was added 8 mL of 1 M sodium (2-dimethylamino-ethoxide) in tetrahydrofuran. After refluxing for 2 hours, the reaction was stripped of tetrahydrofuran and water was added. The product was filtered, washed with water, dried, and recrystallized from chloroform/ether/hexanes to give 266 mg (85%) of 6-(2-dimethylamino-ethoxy)-4-(4-phenoxy-phenylamino)-[1,7]naphthyridine-3-carbonitrile as a yellow solid: melting point 159-161° C.; mass spectrum (m/e): M+H 426.0.
