1H-1,2,4-Triazole → 58905-18-3

Participants

Reaction Steps

To a dimethyl sulfoxide solution (50 ml) of sodium 1,2,4-triazole, generated from 3.25 g (0.047 m) of 1H-1,2,4-triazole, and 1.9 g (0.047 m) of sodium hydroxide, is added 10 g (0.045 m) of 2-hydroxy-2,4-dichlorophenethyl chloride dropwise at 110° under nitrogen. The reaction is stirred at 110° for 11/2 hours. The reaction mixture is poured into water and extracted with methylene chloride. The combined organic extracts are washed with water and dried over MgSO4. Solvent is evaporated to give 8 g of product.
