The general method described in Part E of Example 80 was used with the following modifications. A solution of phenol (1.45 g, 15.4 mmol) in diglyme (10 mL) was added to a cooled mixture of the sodium hydride dispersion (0.59 g, 14.7 mmol) in diglyme (15 mL), and the addition flask was rinsed twice with diglyme (5 mL), which was added to the reaction. A solution of (2-chloro-6-methyl-3-nitropyridin-4-yl)-{2-[3-(pyridin-3-yl)propoxy]ethyl}amine (4.9 g, 14 mmol) was added, and the reaction was heated at 60° C. for 20 hours. Additional reagent prepared from phenol (0.50 g, 5.3 mmol) and 60% sodium hydride (0.21 g, 5.3 mmol) in diglyme was added, and the reaction was heated at 60° C. for 2.5 hours. The reaction was allowed to cool to room temperature and slowly added to 800 mL of water and stirred for one hour to form a bright yellow solid. The solid was isolated by filtration and washed with hexane (50 mL) to provide 7.4 g of (6-methyl-3-nitro-2-phenoxypyridin-4-yl)-{2-[3 -(pyridin-3-yl)propoxy]ethyl}amine as a yellow solid contaminated with water.
