Procedure
To a suspension of 1,2-bis-benzotriazol-1-yl-ethane-1,2-dione (0.100 g, 0.342 mmol) in THF (3.4 mL) was added 3-trifluoromethyl-5,6,7,8-tetrahydro-[1,6]naphthyridine monohydrochloride (0.082 g, 0.342 mmol) and the reaction mixture was stirred at ambient temperature for about 4 h. Et3N (0.05 mL, 0.34 mmol) was added and stirring was resumed for about 1 hour. The reaction mixture was concentrated in vacuo and the residue triturated from hot iPrOAc. The solid was removed by filtration and the filtrate concentrated in vacuo then dissolved in EtOAc (10 mL), washed with 1N aq NaOH (2×5 mL), and saturated aqueous NaHCO3 (10 mL). The organic portion was separated, dried over MgSO4, filtered, and concentrated in vacuo to provide 1-benzotriazol-1-yl-2-(3-trifluoromethyl-7,8-dihydro-5H-[1,6]naphthyridin-6-yl)-ethane-1,2-dione as an orange oil (0.056 g, 0.15 mmol). The crude material was used without further purification.
