The reaction mixture is poured onto 200 ml of ice-water and extracted three times by shaking with 100 ml of toluene each time. The organic phases are combined, subsequently washed with saturated sodium chloride solution and dried over magnesium sulphate. After removing the solvent in vacuo, crude 2-(6-methoxyindan-1-yl)acetonitrile is obtained.
