반응 단계

Anhydrous potassium carbonate (0.17 g, 1.23 mmol) was added to a solution of (3,5-bis-trifluoromethyl-benzyl)-[2-(4-cyclohexylmethyl-piperazin-1-yl)-quinolin-3-yl-methyl]-amine (0.23 g, 0.4 mmol) in anhydrous THF (5 mL). After stirring 0.5 h, ethyl chloroformate (0.06 mL, 0.6 mmol) was added slowly under a nitrogen atmosphere. After stirring at RT for overnight, water (25 mL) was added, and the mixture was extracted with ethyl acetate (3×25 mL). The combined organic phases were washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo to give a colorless liquid. Purification by silica gel chromatography and eluting with 10-30% ethyl acetate/hexane afforded the desired final product as a viscous liquid (0.206 g), yield: 81%.
