Procedure

3-chloro-2-cyano-6-[3-(trifluoromethyl)phenoxy] pyridine (2.58 g, 0.086 mol) was dissolved in 30 ml of 90% sulfuric acid. The obtained solution was heated and stirred at 120° C. for 1.5 hours. Thereafter, the obtained reaction solution was poured into ice water, and then mixed with sodium carbonate to form a weak-acidic solution, thereby precipitating solids. The precipitated solids were filtered out, washed with water, and then dried.
