Reaction Steps

A mixture of 1-benzyloxycarbonyl-2,3-dihydro-6-nitroindole (1.0 g, 3.36 mmol) and tin(II) chloride dihydrate (3.78 g, 16.75 mmol) in ethanol (70 mL) was heated at 70° C., under an atmosphere of nitrogen, for 3 hours. The solution was cooled and the solvent evaporated under reduced pressure to give an off-white solid. The solid was partitioned between water (50 mL) and ethyl actate (100 mL) and the aqueous layer basified (pH 11) with 1M sodium hydroxide solution. The mixture was filtered to remove tin salts and the ethyl acetate was separated, dried (MgSO4) and evaporated under reduced pressure to give the amine as a yellow oil (0.89 g, 99%).
