Reaktionsschritte

A mixture of (1S)-2-chloro-1-(3,4-difluorophenyl)-1-ethanol (net 11.47 g, 59.5 mmol), toluene (25.23 g), sodium hydroxide (2.53 g, 1.06 molar equivalents) and water (24.25 g) was stirred and heated at 40° C. for 1 hour. The organic layer was separated, washed with water, and concentrated under reduced pressure. (2S)-2-(3,4-difluorophenyl)oxirane was obtained as resultant concentrate (net 8.94 g, yield: 96%).
