실험 절차
A mixture of 11 grams of 2-chloro-6-(4-methoxyphenoxy)pyridine, prepared above in Example IX and 100 milliliters of 48 percent hydrobromic acid was heated at reflux overnight. The reaction mixture was cooled and diluted with water. The 4-((6-chloro-2-pyridyl)oxy)phenol separated out as a yellow crystalline solid which was isolated by filtration. The product was recovered in a yield of 10 grams (97 percent of theoretical) and melted at 125°-130° C.
