Reaction Steps
Phenol (0.9 g, 9.5 mmol) was dissolved in sodium hydroxide (50% solution, 12 mL). 5-Nitro-2-chloropyridine (1.5 g, 9.5 mmol) in toluene (15 mL) was added followed by addition of tetra-butylammonium bromide (0.3 g, 0.95 mmol). The reaction mixture was stirred for 16 hours at 20° C. and 5 hours at 80° C. where after it was cooled to room temperature and diethyl ether (100 mL) added. The organic phase was washed with water (5×50 mL), dried (MgSO4), and concentrated in vacuo to give 1.0 g of 5-nitro-2-phenoxypyridine.
