Reaction Conditions

Reaction Steps

2-cyano-6-[3-(trifluoromethyl)phenoxy] pyridine (3.00 g, 0.011 mol) was suspended in about 15 ml of concentrated hydrochloric acid. The obtained suspension was stirred at about 100° C. for about 2 hours. After being allowed to stand for cooling, the obtained reaction solution was mixed with water, and then distributed in ethyl acetate-water. The organic phase separated from the solution was washed with saturated brine, dried with anhydrous sodium sulfate, concentrated and then purified by silica gel column chromatography (eluting solution: ethyl acetate/hexane), thereby obtaining an aimed product.
