The present invention relates to a method for preparing phenyl heterocycle as cyclooxygenase-2 inhibitor useful in the treatment of other cyclooxygenase meditated diseases, which is environmentally harmonious and has an improved productivity. More particularly, it relates to a method for preparing phenyl heterocycle as cyclooxygenase-2 inhibitor, characterized in providing a high-purity compound of Formula 5 with the low cost of production and a simple process, which is harmless to human and environmental pollution due to not generating a halogen gas when preparing, and comprising the steps of lactonization reaction with a compound of Formula 1 as an initiator; substitution reaction; and oxidation reaction.
