Reaktionsschritte

Sodium hydride (60% dispersion in oil, 0.38 g) was added to the mixed solution of ethyl 3-(indol-3-yl)propionate (1.8 g) in DMF (20 ml) and THF (20 ml) under ice-cooling. The reaction mixture was stirred at room temperature for 10 minutes, to which were added 2,4-dichlorobenzyl bromide (1.8 g) and sodium iodide (0.3 g). The reaction mixture was stirred at room temperature for 3 hours and then poured into water, and the mixture was extracted with IPE. The organic layer was washed with water, then dried and concentrated. The residue was dissolved in ethanol (30 ml), which was stirred at 50° C. for 2 hours in the presence of water (10 ml) and sodium hydroxide (1 g). The reaction mixture was concentrated, made acidic, and then extracted with ethyl acetate. The organic layer was washed with water, then dried and concentrated. The residue was recrystallized from ethyl acetate-IPE to obtain the entitled compound (2.4 g).
