Reaction Steps

A mixture of 1-(2-phthalimidoethyl)-4-(3-indolyl)piperidine (6.3 g) and hydrazine monohydrate (2.2 g) in ethanol (250 ml) was refluxed for 70 minutes. After cooling, the reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was treated with 5% sodium hydroxide solution (300 ml) and extracted with ethyl acetate (300 ml). The organic layer was washed with a saturated sodium chloride solution and dried over magnesium sulfate. The evaporation of solvent gave 1-(2-aminoethyl)-4-(3-indolyl)piperidine (3.74 g).
