実験手順
To a solution of 2-chloro-N-[2-(2H-[1,2,4]triazol-3-yl)-4-trifluoromethoxy-phenyl]-acetamide (3.15 g, 9.82 mmol) in dioxane (100 mL) was added aqueous sodium hydroxide (32%, 2.18 mL, 23.6 mmol) and the reaction mixture was stirred for 19 h at ambient temperature. It was poured onto aqueous ammonium chloride (1M, 50 mL) and the organic solvent was removed by destillation. The resulting suspension was filtered and the solid was washed with ice-cold water (50 mL). Drying in vacuo afforded the title compound (682 mg, 24%) as a light yellow solid. MS: m/e=285.0 [M+H]+.
