2,6-Difluoro-3-nitropyridine (5.00 g) is dissolved in acetonitrile (10 ml) and 1-benzyl-4-ethylaminopiperidine (EXAMPLE 11, 6.81 g) dissolved in 10 ml of acetonitrile is added via cannula. Then an additional 58 ml of acetonitrile is added and the reaction is cooled to 0°. Then 5.1 g of potassium carbonate is added and the reaction is stirred 10 min and allowed to warm to 20°-25°. After 6 hrs, the reaction is poured into water, extracted with ethyl acetate, washed with saline and dried over sodium sulfate. Flash column chromatography (silica gel; 5% ethyl acetate/hexane to 10% ethyl acetate/hexane) gives the title compound, NMR (300 MHz, CDCl3) 8.22, 7.37-7.23, 6.25, 3.66, 3.55, 3.50, 3.01, 2.10, 1.95, 1.83 and 1.09δ.
