Reaction Steps
To a solution of 2-(5-nitro-1H-indol-2-yl)propan-1-ol (0.13 g, 0.60 mmol) in ethanol (5 mL) was added tin chloride dihydrate (0.67 g, 3.0 mmol). The mixture was heated in the microwave at 120° C. for 1 h. The mixture was diluted with ethyl acetate before water and saturated aqueous NaHCO3 were added. The reaction mixture was filtered through a plug of celite using ethyl acetate. The organic layer was separated from the aqueous layer, dried over Na2SO4, filtered and evaporated under reduced pressure to give 2-(5-amino-1H-indol-2-yl)propan-1-ol (0.093 g, 82%).
