Participants

Reaction Steps

A mixture of 1.5 grams (0.0068 mole) 2-(5-chloropyridin-2-yloxy)phenol, 1.3 grams 2-chloro-5-nitropyridine, 1.0 grams potassium carbonate, and 40 ml of methyl ethyl ketone was heated at reflux overnight. Excess water was added and the aqueous mixture extracted with 200 ml of ethyl ether. The ether extract was washed with saturated NaHCO3, H2O, brine, dried (MgSO4), filtered, and the solvent was evaporated to yield a solid which was suspended in hexane and filtered. Yield 1.4 grams, m.p. 82°-84°; ir (Nujol): 6.15, 6.25 (C=N, NO2), 13.30 (broad), 13.70 microns; NMR (CDCl3): δ6.55 (s, ArH), 6.75 (d, ArH), 6.95 (s, ArH), 7.35 (s, 4H, ArH), 7.40-7.65 (m, ArH), 8.05 (d, ArH), 8.40 (AB quartet, ArH), 8.95 (d, ArH).
