Procedure
A solution of benzyl 2,2-difluorocyclohexylcarbamate (38 mg, 0.14 mmol) in 6 N HCl (2 mL) was heated at 100° C. for 2 h. The cooled reaction mixture was extracted with ether (3×1 mL) and the combined organic layers were concentrated to give 2,2-difluorocyclohexanamine hydrochloride as a light brown solid (23 mg, 96% crude).
