Hydrochloric Acid → 7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-amine

Participants

Reaction Steps

To a solution of the crude N-(7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-yl)-1,1-diphenylmethanimine in THF (30 mL) was added LM hydrochloric acid (29 mL, 29.17 mmol) at room temperature, and the mixture was stirred at room temperature for 30 min. The pH of the reaction mixture was adjusted to >7 with sodium hydroxide, and the mixture was extracted with ethyl acetate (×2). The organic layer was washed with 10% brine, dried over sodium sulfate, and concentrated under reduced pressure to give the crude 7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-amine as an orange oil.
