Procedure

To a mixture of 2-(2-chloro-benzylamino)-thiazol-4-one (40.9 mg, 0.17 mmol) (see Example 2), AcONa (160 mg, 1.95 mmol), and 6-formyl-4-isopropoxy-[1,5]naphthyridine-3-carbonitrile (53.1 mg, 0.22 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 2 hrs. The reaction mixture was then cooled to r.t. and triturated with water. The solid was collected by filtration and washed with water acetone and ether to give 6-[2-(2-chloro-benzylamino)-4-oxo-4H-thiazol-5-ylidenemethyl]-[1,5]naphthyridine-3-carbonitrile as a dark brown solid (20.8 mg, 30.1%). HR-ES (+) m/e calcd for C20H12ClN5OS (M+H)+ 406.0524. found 406.0525.
