Reaction Steps

To a mixture of 2-(3-chloro-4-fluoro-benzylamino)-thiazol-4-one (41.4 mg, 0.16 mmol) (prepared as described below) AcONa (160 mg, 1.95 mmol), and 6-formyl-[1,5]naphthyridine-3-carbonitrile (33.6 mg, 0.18 mmol) (see Example 11) in a sealed tube was added AcOH (0.3 mL). The reaction mixture was heated to 120° C. (oil bath) for 3 hrs. The reaction mixture was then cooled to r.t. and triturated with water. The solid was collected by filtration and washed with water, AcOEt and ether to give 6-[2-(3-chloro-4-fluoro-benzylamino)-4-oxo-4H-thiazol-5-ylidenemethyl]-[1,5]naphthyridine-3-carbonitrile as a light brown solid (30.6 mg, 45.1%). HR-ES (+) m/e calcd for C20H11FClN5OS (M+H)+ 424.0430. found 424.0431.
