Reaction Steps

To a suspension of 2-[2-(3-fluoro-phenyl)-ethylamino]-thiazol-4-one (38.1 mg, 0.16 mmol), and 1,5-naphthyridine-6-carboxaldehyde (31.6 mg, 0.2 mmol) in toluene (1 mL) in a microwave tube were added benzoic acid (2.0 mg, 0.02 mmol) and piperidine (1.7 uM, 0.02 mmol). The reaction mixture was heated to 130° C. with microwave for 10 min., then cooled to r.t. and diluted with toluene. The solid was collected by filtration and washed with toluene, MeOH and ether to give 2-[2-(3-fluoro-phenyl)-ethylamino]-5-[1,5]naphthyridin-2-ylmethylene-thiazol-4-one as a brown solid (22.3 mg, 36.9%). HR-ES (+) m/e calcd. for C20H15FN4OS: (M+H)+ 379.1024. Found: 379.1024.
