実験手順

To a solution of 2-(5-bromo-2-chlorophenyl)-propan-2-ol (500 mg, 2 mmol, 1 eq) in toluene (5 ml) was added a catalytic amount of p-toluenesulfonic acid (38 mg, 0.2 mmol, 0.1 eq) and the solution was refluxed under a Dean-Stark H2O separator overnight. The reaction mixture was allowed to cool to RT and was diluted with ether. The mixture was washed with sat. NaHCO3-solution and brine, dried (MgSO4), filtered and concentrated in vacuo to give the desired product (357 mg, 77%) as a colorless oil which did not require further purification.
