Reaction Steps

To a solution of 1-(tert-butoxycarbonyl)-4-[2-(cyclohexyloxy)ethyl]piperidine (182 mg, 0.59 mmol) in MeOH (2 mL) was added 2N anhydrous HCl/ether (0.75 mL, 1.5 mmol). The reaction mixture was stirred overnight. After evaporation, the residue was dissolved in deionized water. EtOAc was used to wash the aqueous layer before the pH was altered to approx. 9-10. The aqueous layer was extracted three times with CH2Cl2 and dried over Na2SO4. After evaporation, the product (38.0 mg, 30%) was obtained as a colorless oil. 1H NMR (CDCl3, 400 MHz) δ 3.46-3.29 (m, 2H), 3.16 (1, 2H), 3.02 (m, 2H), 2.56 (m, 2H), 2.17 (br, 1H), 1.88 (m, 2H), 1.71-1.64 (m, 4H), 1.52-1.42 (m, 4H), 1.25-1.22 (m, 3H), 1.99-1.13 (m, 2H), 1.11-1.08 (m, 2H); 13C NMR (CDCl3, 100 MHz) δ 64.8, 46.3, 37.0, 33.2, 32.8, 32.0, 27.2, 25.4, 23.9.
