Reaction Steps
A solution of 3,5-dinitro-benzonitrile (5 g, 25.9 mol), 5-chloro-pyridin-3-ol (3.35 g, 25.9 mol) and K2CO3 (7.2 g, 52 mol) in DMF (150 mL) was heated at 100° C. overnight. The mixture was concentrated in vacuo and the residue was poured into water. The aqueous layer was extracted with ethyl acetate (3×150 mL) and the combined organics were washed with brine, dried (Na2SO4), concentrated in vacuo and purified by silica gel chromatography to afford 3-(5-chloro-pyridin-3-yloxy)-5-nitro-benzonitrile (3.1 g, 44% yield). 1H NMR (400 MHz, DMSO-d6) δ 8.56 (s, 1H), 8.51 (s, 1H), 8.47 (s, 1H), 8.22 (s, 1H), 8.19 (s, 1H), 7.87 (s, 1H).
