Reaction Steps

A mixture of 3-(2-azidoethyl)-6-chloro-5-methyl-2-(triethylsilyl)-1H-indole (0.654 g; 1.87 mmol) and triphenylphosphine (0.737 g; 2.81 mmol) in methanol (10 mL) was stirred at 70° C. for 2 hours. The reaction mixture was concentrated under reduced pressure and the residue was dissolved in a solution of tetrabutylamonium fluoride (5.62 mL 1M) in THF and stirred at room temperature for 36 hours and concentrated under reduced pressure to yield 2-(6-chloro-5-methyl-1H-indol-3-yl)ethanamine, which was used without any further purification.
