Reaktionsschritte

46.4 g of oxalyl chloride and 2 drops of dimethyl-formamide were added to 48.3 g of monomethyl succinate dissolved in 840 ml of dichloroethane. 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. After the organic layer was collected by separation, washed with water and dried, the solvent was removed to obtain 51.8 g of 2-(acetylaminomethyl)-5-(3-methoxycarbonylpropionyl)indane. m.p.: 139° to 140° C.
