Reaction Steps

To a suspension of potassium t-butoxide (1.5 g) in THF (15 mL) was added 3-chloro-5-hydroxypyridine (1.79 g, mmol). To this solution was added a solution of N-ethyl-2-chloro-5-nitrobenzamide (2.76 g, mmol) in THF (15 mL). The resulting mixture was heated at 50° C. for 84 hr. After cooling, the reaction mixture was diluted into a mixture of water and ether. Solids were collected by filtration, washed with water then with ether, and dried under vacuum to afford N-ethyl 5-nitro-2-(3-chloro-5-pyridyloxy)benzamide (2.0 g, 52%). mp 165-167° C.
