Procedure

To a mixture of 2-(3-chloro-4-fluoro-benzylamino)-thiazol-4-one (41.4 mg, 0.16 mmol) (see Example 19), AcONa (160 mg, 1.95 mmol), and 8-isopropoxy-[1,5]naphthyridine-2-carbaldehyde (38.9 mg, 0.18 mmol) (see Example 20) in a sealed tube was added AcOH(0.3 mL). The reaction mixture was heated to 100° 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 2-(3-chloro-4-fluoro-benzylamino)-5-(8-isopropoxy-[1,5]naphthyridin-2-ylmethylene)-thiazol-4-one as a light brown solid (63.5 mg, 86.9%). HR-ES (+) m/e calcd for C22H18FClN4O2S (M+H)+ 457.0896. found 457.0897.
