Reaction Steps

After heating at reflux a mixture of 1.5 grams (0.0067 mole) 2-(5-chloropyrimidin-2-yloxy)phenol, 1.2 grams potassium carbonate, 1.3 grams 2-chloro-5-nitropyridine and 40 ml of methyl ethyl ketone, the reaction mixture was poured into excess H2 0 and the aqueous mixture extracted with ethyl ether (200 ml). The ether layer was washed with saturated NaHCO3, H2O, brine, dried (MgSO4), filtered, and evaporated to yield 2.3 grams of a yellow-orange oil which was purified by silica gel column chromatography (CH2Cl2 as the eluent). NMR (CDCl3): δ6.90 (d, 1H, pyridine ring proton), 7.35 (s, 4H, ArH), 8.25-8.50 (m, 1H, pyridine ring proton), 8.45 (s, 2H, pyrimidine ring protons), 8.95 (d, 1H, pyridine ring proton).
