Reaction Steps

Ethyl 4,6-dichloro-1,5-naphthyridine-3-carboxylate (0.5 g, 1.84 mmol) and tert-butyl 4-(4-amino-2-(trifluoromethyl)phenyl)piperazine-1-carboxylate (0.766 g, 2.22 mmol) were dissolved in a mixture of dichloromethane (5 mL) and tert-butanol (5 mL), to the system added potassium carbonate (0.612 g, 4.43 mmol). The reaction mixture was stirred at room temperature for 24 h, suction filtrated, the solid was washed with 30 mL of dichloromethane, and the resulting wash solution and the filtrate were combined, concentrated under reduced pressure, and the resulting residue was recrystallized from diethyl ether to give 0.73 g of a pale yellow solid.
