実験手順

A mixture of 3-(2-azidoethyl)-2-(triethylsilyl)-5-(trifluoromethyl)-1H-indole (0.400 g; 1.09 mmol) and triphenyl phosphine (0.427 g; 1.63 mmol) in methanol (5 mL) was stirred at 70° C. for 2 hours. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in a solution of tetrabutylammonium fluoride (3.26 mL, 1M) in THF and stirred at room temperature for 36 hours and concentrated under reduced pressure to yield 2-(5-(trifluoromethyl)-1H-indol-3-yl)ethanamine, which was used without any further purification.
