HCID 451589311-(4,4-Difluorocyclohexyl)methanamine hydrochloride

実験手順

tert-Butyl[(4,4-difluorocyclohexyl)methyl]carbamate (505 mg, 2.03 mmol) was stirred in 5 mL of 1M HCl/AcOH at rt for 2 h. The solvent was evaporated. The residue washed with ether, filtered and dried. Yield: 330 mg (88%); 1H NMR (400 MHz, CD3OD) δ 1.28-1.40 (m, 2 H), 1.71-1.82 (m, 2 H), 1.84 (d, J=3.12 Hz, 2 H), 1.86-1.89 (m, 1 H), 2.03-2.15 (m, 2 H), 2.85 (d, J=7.03 Hz, 2 H).
