Reaction Steps

To a suspension of 2-(2-chloro-6-methyl-benzylamino)-thiazol-4-one (40.8 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-6-methyl-benzylamino)-5-[1,5]naphthyridin-2-ylmethylene-thiazol-4-one as a brown solid (32.9 mg, 52.1%). HR-ES (+) m/e calcd. for C20H15ClN4OS: (M+H)+ 395.0728. Found: 395.0728.
