Reaction Steps

A 1M tetrahydrofuran-solution of borane tetrahydrofuran (2.62 ml) was added dropwise to a solution of 1-{5-[(cyclopropylamino)methyl]-1-methyl-1H-indol-3-yl}-3-methoxy propan-1-one (150 mg) in tetrahydrofuran (2.5 ml) under ice-cooling and the mixture was stirred at room temperature for 15 hours. A 5N aqueous solution of sodium hydroxide (2.5 ml) and methanol (1.25 ml) were added to the reaction mixture and it was stirred at 50° C. for 24 hours. The reaction mixture was cooled to room temperature, extracted with diethyl ether. The organic layer was washed with saturated brine, dried over sodium sulfate and concentrated in vacuo. The resulted residue was purified with a silica gel column chromatography (eluting solvent: chloroform to chloroform/methanol=5/1) to give N-{[3-(3-methoxypropyl)-1-methyl-1H-indol-5-yl]methyl}cyclopropanamine (107 mg) as a colorless oil.
