Procedure

Ethyl [3-tert-Butyl-1-(2-methoxyethyl)-1H-1,2,4-triazol-5-yl]acetate (Preparation 115, 23.1 g, 0.086 mol) was dissolved in methanol (150 mL), and 1.9N LiOH (68 mL, 0.13 mol) was added. The mixture was stirred at 0° C. for 30 minutes and concentrated in vacuo at 30° C. Water (70 mL) was added. The resulting mixture was washed with ether (3×100 mL) and neutralized with titrated 2.6N HCl (49.6 mL, 0.13 mol). The resulting precipitate was filtered, washed with water, hexane and dried to afford the title compound (16.54 g, 80%).
