Procedure

To a solution of 4-benzyloxy-3-[(4-(N-methyl-N-(1-ethoxycarbonylcyclopent-1-yl)amino)-3,5,6-trifluoropyridin-2-yl)oxy]benzonitrile (0.87 g, 1.7 mmol) in DMSO (17 mL) was added 3-(1-methylimidazolin-2-yl)phenol (0.32 g, 1.8 mmol) and cesium carbonate (0.7 g, 2.1 mmol). The resultant mixture was stirred at 35° C. After 4 days, the mixture was 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 0.5 M aqueous KOH solution (100 mL), brine (100 mL), dried over MgSO4, filtered, and concentrated in vacuo to afford 4-benzyloxy-3-[(4-(N-methyl-N-(1-ethoxycarbonylcyclopent-1-yl)amino)-6-(3-(1-methylimidazolin-2-yl)phenoxy)-3,5-difluoropyrid in-2-yl)oxy]benzonitrile as a solid foam: NMR (CDCl3) 7.4-6.8 (m, 12), 5.0 (s, 2), 4.2 (q, 2), 3.9 (t, 2), 3.5 (t, 2), 3.2 (s, 3), 2.8 (s, 3), 2.4-1.7 (m, 8), 1.3 (t, 3) ppm.
