実験手順: 4,4-Difluoro-cyclohexylamine hydrochloride (1.0 g, 5.8 mmol, 1 equiv.) was added to a mixture of NaOH (1.5 g, 37 mmol, 6.3 equiv.) and tetrabutylammonium hydrogen sulfate (40 mg, 0.12 mmol, 0.02 equiv.) in water (2.5 ml), chloroform (3 ml, 37 mmol) 6.3 equiv.) and DCM (5 ml). The mixture was stirred at room temperature for 72 h and the crude extracted with DCM. The product was isolated via Kieslgel chromatography. the crude extracted with DCM The product was isolated via Kieslgel chromatography
