Sodium Hydroxide → 6-fluoro-2,3-dihydro-1H-indole

関与物質

反応手順

Under a nitrogen atmosphere 0.29 g (4.6 mmol) sodium cyanoborohydride were added batchwise to 0.54 g (4.0 mmol) 6-fluoroindole in 5.0 mL glacial acetic acid and the mixture was stirred for 30 min. Then the reaction mixture was poured onto a 4N aqueous sodium hydroxide solution and extracted with EtOAc. The combined organic phases were washed several times with saturated sodium hydrogen carbonate solution, dried on sodium sulphate and evaporated down.
