Step 3
General procedure: A solution of 3-(1H-indol-3-yl)-1-methyl pyrrolidine-2,5-dione ( 8.8 g, 38.5 mmoles) in tetrahydrofuran (20 ml) was added to cooled and stirred suspension of lithium aluminum hydride (3.7 g, 97.3 mmoles) in tetrahydrofuran (30 ml) slowly and the resulting slurry was heated at reflux for 4 hrs. After the completion of reaction, the reaction mixture was cooled to 10 oC, poured on to chilled water (100 ml) and stirred for 30 min. The slurry, thus obtained, was filtered, layers separated and the aqueous layer was extracted with ethyl acetate (2 x 70 ml). The combined organic layer was washed with brine solution (50 ml) and dried over sodium sulfate. Organic volatiles were removed under reduced pressure. The residual mass, thus obtained, was purified by flash chromatography to afford 3-(1-methyl-pyrrolidin-3-yl)-1H-indole (5.4 g, 70 percent). 70%

The residual mass, thus obtained, was purified by flash chromatography to afford 3-(1-methyl-pyrrolidin-3-yl)-1H-indole (5.4 g, 70 percent). With lithium aluminium tetrahydride

Step 3
General procedure: A solution of 3-(1H-indol-3-yl)-1-methyl pyrrolidine-2,5-dione ( 8.8 g, 38.5 mmoles) in tetrahydrofuran (20 ml) was added to cooled and stirred suspension of lithium aluminum hydride (3.7 g, 97.3 mmoles) in tetrahydrofuran (30 ml) slowly and the resulting slurry was heated at reflux for 4 hrs. After the completion of reaction, the reaction mixture was cooled to 10 oC, poured on to chilled water (100 ml) and stirred for 30 min. The slurry, thus obtained, was filtered, layers separated and the aqueous layer was extracted with ethyl acetate (2 x 70 ml). The combined organic layer was washed with brine solution (50 ml) and dried over sodium sulfate. Organic volatiles were removed under reduced pressure. The residual mass, thus obtained, was purified by flash chromatography to afford 3-(1-methyl-pyrrolidin-3-yl)-1H-indole (5.4 g, 70 percent). With lithium aluminium tetrahydride
