Reaction Steps

Ethyl 3-cyano-2,4,5-trifluorobenzoate (3.35 g, 14.6 mmol) was suspended in glacial acetic acid (5 mL). Concentrated hydrochloric acid (10 mL) was added thereto, and the mixture was stirred at 100° C. for 4 hours. While cooling with ice, water (100 mL) was added to the reaction mixture. Subsequently, the resultant mixture was extracted with chloroform (100 mL×4), followed by drying with sodium sulfate anhydrate. After filtration, the filtrate was concentrated under reduced pressure. The residue was recrystallized from chloroform/n-hexane, to thereby yield the title compound as a white solid (2.86 g, 97%).
