Versuchsvorschrift
44 g (182 mmol) of 7-(2-fluorobenzoyl)indoline and 800 ml of methylene chloride are poured into a reactor equipped with a central stirrer, a condenser provided with a calcium chloride guard tube, a dipping thermometer, a nitrogen inlet and a pressure-equalizing dropping funnel. 27.9 g (182 mmol) of N-chlorosuccinimide are added gradually and the mixture is stirred over a warm temperature. The mixture is washed with saturated sodium bicarbonate solution and then with water, dried and evaporated. It is chromatographed on silica, eluting with methylene chloride. 42 g (84% yield) are obtained. The product is obtained in the form of a foam which has no definite melting point. TLC: H2CCl2Rf=0.70.
