実験手順
A suspension of trans (4-methanesulfonyl-cyclohexyl)-carbamic acid tert-butyl ester (0.40 g, 1.40 mmol) in DCM (5 mL) was treated with trifluoroacetic acid (5 mL) and the mixture was stirred at ambient temperature for 30 minutes then concentrated under vacuum. The residue was azeotroped with toluene (×2) and the resulting oil was triturated (diethyl ether) to provide a solid which was washed with ether and dried to give 386 mg (93%) of trans 4-methanesulfonyl-cyclohexylamine trifluoroacetic acid salt as a white solid. 1H NMR (400 MHz, DMSO) δ: 7.86 (s, 3H), 3.11-2.98 (m, 2H), 2.92 (s, 3H), 2.18-2.02 (m, 4H), 1.56-1.43 (m, 2H), 1.43-1.28 (t, 2H).
