Reaktionsschritte

To a solution of 3-(3,4-dichlorophenyl)-2-propyn-1-ol (2.980 g, P7, from Method A and B described for P7) in dry DCM (74 mL) and Dess-Martin periodinane (9.43 g) was added. The mixture was stirred at room temperature over night. NaS2O3 (19 g) and NaHCO3 saturated solution were then added to the mixture and it was stirred at room temperature for 1 hour. Then the organic phase was separated and washed with brine. The organic layer was dried and concentrated under reduced pressure to give the crude title product (2.9 g) that was used without further purification.
