Komponenten

Versuchsvorschrift

A mixture of 12.9 g of 2-isopropylthiobenzoyl chloride and 20 ml of absolute toluene is added dropwise to a mixture of 4.44 g of 3-hydroxyoxetane, 6.64 g of pyridine and 60 ml of absolute toluene at a temperature of 15°to 20° C. The suspension formed is stirred at a temperature of 20°-25° C. for 2 hours and at a temperature of 40°-45° C. for a further 3 hours. Adding water to the reaction mixture, washing the organic phase with water and drying and evaporating it gives 12.6 g of oxetan-3-yl 2-isopropylthiobenzoate as a pale yellow oil.
