Versuchsvorschrift

To a solution of 3.05 g (11.0 mmol) of the product of Example 121 in 15 mL of DMF was added 0.484 g (12.1 mmol) of 60% sodium hydride. The resulting mixture was stirred for 30 min at room temperature and then 1.89 g (10.0 mmol) of 2-fluoro-3-(trifluoromethyl)benzonitrile in 2 mL of DMF was added. The reaction mixture was stirred at 90° C. for 18 hr, poured into water and extracted with ether. The combined organics were washed with water, brine, dried over MgSO4, filtered and concentrated in vacuo. The crude solid was triturated with ether to provide 3.33 g (75%) of the desired product as a white solid. Electrospray Mass Spec 447.2(M+H).
