Versuchsvorschrift

2-(2-chlorophenyl)-2-hydroxyacetonitrile (16.8 g, 0.1 mol) and 4-toluene sulfonyl chloride (21 g, 0.11 mol) was dissolved in acetonitrile (80 mL) in a suitable reaction flask, and Et3N (20 g, 0.2 mol) was added to the reaction dropwise at 0-25° C. Then the solution was stirred at room temperature for 5 h and afterwards refluxed until the reaction was completed by TLC monitoring. The acetonitrile was recovered and reaction mixture was diluted by water and extracted with butyl acetate. The organic layer was washed repeatedly with water and the butyl acetate was removed under reduced pressure giving the target product (30 g, yield 93.75%).
