1H-1,2,4-Triazole → HCID 3823094, Verbindung

A solution of chloromethyl ethyl ether (23.5 g) in toluene (300 ml ), was added dropwise, over an hour, to a solution of 1,2,4-triazole (50 g) in toluene (50 ml), and the reaction stirred at room temperature for 18 hours. On cooling, the reaction mixture was evaporated to dryness in vacuo, the residue triturated with dichloromethane, and the resulting suspension filtered. The filtrate was evaporated in vacuo and purified by column chromatography over silica gel (5/95 methanol/dichloromethane) to afford the title compound as a colorless oil, 23.9 g.
