Ethanol → HCID 10872742, compound

Participants

Reaction Steps

At room temperature, a mixture of 1.72 g (5 mmol) of 2-(1-chloro-cyclopropyl)-1(2-chlorophenyl)-3-(5-mercapto-1,2,4-triazol-1-yl)-propan-2-ol in 20 ml of absolute tetrahydrofuran is admixed with stirring with 0.24 g (6 mmol) of sodium hydride (60% strength in paraffin oil) and stirred for 30 minutes. 0.72 ml (10 mmol) of acetyl chloride are then added and the reaction mixture is stirred at room temperature for a further 4 hours. The reaction mixture is then admixed with 1 ml of ethanol and concentrated under reduced pressure. The residue that remains is extracted repeatedly with dichloromethane. The combined organic phases are concentrated under reduced pressure. In this manner, 1.8 g (94% of theory) of 2-(1-chloro-cyclopropyl)-1-(2-chlorophenyl)-3-(5-acetylmercapto-1,2,4-triazol-1-yl)-propan-2-ol are obtained in the form of an oil.
