Procedure

3.58 g (8.91 mmol) of ethyl[3-(4-chlorophenyl)-4-(4-methoxyphenylmethyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-acetate from Example 78A are placed in 40 ml methanol and stirred overnight at room temperature with 4 ml of 20% aqueous potassium hydroxide. It is adjusted to pH 6 with 1 N hydrochloric acid and purified by preparative HPLC [Method 12]. 2.71 g (81% of theory) of the target compound are thus obtained.
