実験手順

To a mixture of 2-[(thiophen-2-ylmethyl)-amino]-thiazol-4-one one (34.0 mg, 0.16 mmol) (see Example 4), 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 4.5 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 5-(8-isopropoxy-[1,5]naphthyridin-2-ylmethylene)-2-[(thiophen-2-ylmethyl)-amino]-thiazol-4-one as a light brown solid (29.8 mg, 45.4%). HR-ES (+) m/e calcd for C20H18N4O2S2 (M+H)+ 411.0944. found 411.0945.
