Participants

Reaction Steps

20 g (0.062 mole) of (4-chlorophenylthio)-(imidazol-1-yl)-(3,3-dimethyl-tetrahydrofuran-2-ylidene)-methane (Example I-1) and 28 g (0.25 mole) of 30% strength hydrogen peroxide in 200 ml of glacial acetic acid are stirred at 50° C. for 20 hours. The reaction mixture is then poured into 1.5 liter of water and extracted with methylene chloride. The organic phase is dried over sodium sulphate and concentrated. 10.7 g (49% of theory) of (4-chlorophenylsulphonyl)-(imidazol-1-yl)-(3,3-dimethyltetrahydrofuran-2-ylidene)-methane of melting point 192°-194° C. are obtained.
