Reaction Steps

To a suspension of 2-(2-chloro-4-fluoro-benzylamino)-thiazol-4-one (41.4 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 15 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-chloro-4-fluoro-benzylamino)-5-[1,5]naphthyridin-2-ylmethylene-thiazol-4-one as a brown solid (30.5 mg, 47.8%). HR-ES (+) m/e calcd. for C19H12FClN4OS: (M+H)+ 399.0477. Found: 399.0476.
