Procedure:
trans 4-(Aminomethyl)cyclohexane carboxylic acid ethyl ester (CAS 35879-53-9) (222 mg, 1.0 mmole, 1.0 eq) was dissolved in dichloromethane (5 mL) and triethyl amine (0.35 mL, 2.5 mmole, 2.5 eq) and acetic anhydride (143 μL, 1.50 mmole, 1.5 eq) was added. The reaction was stirred overnight and was complete in 18 hours. The reaction was diluted with dichloromethane and washed twice with dilute aqueous hydrochloric acid. The organic was dried over sodium sulfate, filtered and evaporated to give the title compound in quantitative yield. 1H NMR (500 MHz, DMSO-d6): δ 7.76 (s, 1H), 4.01 (q, 2H), 2.85 (t, 2H), 2.17 (m, 1H), 1.86 (m, 2H), 1.77 (s, 3H), 1.69 (m, 2H), 1.24 (m, 3H), 1.13 (t, 3H), 0.88 (m, 2H).
