Trifluoroacetic acid → 4-(4-Chlorophenyl)cyclohexan-1-amine

Participants

Reaction Steps

To a solution of tert-butyl 4-(4-chlorophenyl)cyclohexylcarbamate (0.760 g, 2.45 mmol) in dichloromethane (5 ml) was added trifluoroacetic acid (5 ml), and the reaction was stirred at ambient temperature for 2 hours. The reaction was concentrated, taken up in water, and 1M NaOH was added until the pH was >13. The aqueous layer was extracted twice with dichloromethane, and the combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated to yield 371 mg of the title compound (72.1% yield).
