실험 절차

To a solution of 4-(N-methyl-N-(1-ethoxycarbonylcyclopent-1-yl)amino)-2,3,5,6-tetrafluoropyridine (0.89 g, 2.8 mmol) in acetonitrile (30 mL) was added 2-benzyloxy-5-cyanophenol (0.63 g, 2.8 mmol) and cesium carbonate (1.2 g, 3.6 mmol). The resultant mixture was stirred at 60° C. for 1 day. The mixture was then cooled to ambient temperature and poured into 100 mL of water and 100 mL of ethyl acetate. The aqueous layer was separated and extracted with another 100 mL of ethyl acetate. The combined organic extracts were washed with 1M aqueous KOH solution (100 mL), brine (100 mL), dried over MgSO4, filtered, and concentrated in vacuo to afford a yellow oil. Purification by flash chromatography on silica gel afforded 0.87 g (60% yield) of 4-benzyloxy-3-[(4-(N-methyl-N-(1-ethoxycarbonylcyclopent-1-yl)amino)-3,5,6-trifluoropyridin-2-yl)oxy]benzonitrile, a compound of formula (G), as a clear, colorless oil: NMR (CDCl3) 7.6-7.1 (m, 8), 5.2 (s, 2), 4.2 (q, 2), 3.1 (s, 3), 2.3-1.6 (m, 8), 1.3 (t, 3) ppm.
