Reaction Steps

To a suspension of 2-[(thiophen-2-ylmethyl)-amino]-thiazol-4-one (34.0 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 120° C. with microwave for 5 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 5-[1,5]naphthyridin-2-ylmethylene-2-[(thiophen-2-ylmethyl)-amino]-thiazol-4-one as a light brown solid (19.7 mg, 34.9%). HR-ES (+) m/e calcd. for C17H12N4OS2: (M+H)+ 353.0526. Found: 353.0526.
