Procedure

To a solution of 2,2,2-trifluoro-N-(3-(3-(3-hydroxy-3-propylhex-1-ynyl)phenyl)propyl)acetamide (2.6 g, 7.0 mmol) in MeOH (50 mL) was added concentrated aqueous NH4OH (ca. 25 mL) and the solution was stirred at room temperature overnight. More concentrated aqueous NH4OH (5 mL) was added and the mixture was stirred overnight. The volatiles were removed by concentration under reduced pressure and the residue was extracted twice with EtOAc. The organic solution was washed with water and brine, dried over Na2SO4 and concentrated under reduced pressure. Purification by flash chromatography (0 to 20% (20% 7M NH3 in MeOH-EtOAc)-EtOAc gradient) gave 4-((3-(3-aminopropyl)phenyl)ethynyl)heptan-4-ol as a clear oil. Yield (1.58 g, 83%): 1H NMR (400 MHz, DMSO-d6) δ 7.14-7.26 (m, 4H), 5.12 (s, 1H), 2.56 (t, J=7.2 Hz, 2H), 2.47 (t obs, J=7.2 Hz, 2H), 1.42-1.63 (m, 12H), 0.90 (t, J=7.2 Hz, 6H).
