Reaktionsschritte

To 48.3 g of methyl hydrogen succinate dissolved in 840 ml of dichloroethane were added 46.4 g of oxalyl chloride and 2 drops of dimethylformamide. The mixture was stirred at room temperature for 5 hours. Then, under ice cooling, 34.6 g of 2-(acetylaminomethyl)indane dissolved in 280 ml of dichloroethane and 97.6 g of anhydrous aluminum chloride were added to the reaction mixture. After the mixture was stirred for 1 hour, the reaction mixture was poured into ice water. The organic layer was collected by separation, washed with water and dried, and the solvent was removed to obtain 51.8 g of 2-(acetylamino)methyl-5-(3-methoxycarbonylpropionyl)indane.
