实验过程

In a 25 mL round-bottomed flask, cis-(3-cyano-cyclohexyl)-carbamic acid tert-butyl ester (212 mg, 0.945 mmol) was combined with dichloromethane (3 ml) to give a colorless solution. Trifluoroacetic acid (0.9 mL, 11.7 mmol) was added to give a yellow solution which was stirred at room temperature for 1.5 h. The reaction mixture was then concentrated under reduced pressure. The residue was azeotroped with toluene to afford 321 mg of cis-3-aminocyclohexanecarbonitrile trifluoroacetate as a crude solid that was taken to the next step without purification. 1H NMR (300 MHz, DMSO-d6) δ: 7.96 (br. s., 3H), 2.93-3.14 (m, 1H), 2.87 (tt, J=12.2, 3.5 Hz, 1H), 2.22 (d, J=12.1 Hz, 1H), 1.96 (d, J=10.2 Hz, 1H), 1.87 (d, J=11.3 Hz, 1H), 1.68-1.81 (m, 1H), 1.49 (q, J=12.1 Hz, 1H), 1.18-1.41 (m, 3H).
