4.88 g (15.9 mmol) of ethyl[3-(4-chlorophenyl)-4-allyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-acetate from Example 214A are placed in 48 ml methanol and stirred with 5 ml 20% aqueous potassium hydroxide for 2 hrs at room temperature. The solution is concentrated to ca. one half, then diluted with water and extracted with ethyl acetate. The aqueous phase is acidified with ca. 2 ml of conc. hydrochloric acid and extracted twice with 100 ml ethyl acetate each time. The last organic extracts are combined, dried over sodium sulphate, filtered and concentrated in vacuo. After drying in high vacuum, 4.20 g (90% of theory) of the target compound are thus obtained.
