Procedure
To a solution of tert-butyl 4-(4-(benzyloxy)phenyl)-3-hydroxypiperidine-1-carboxylate (100 mg, 0.26 mmol) in 10 mL diethyl ether was added 4 M HCl in dioxane (1.3 mL, 5.2 mmol) and the resulting mixture was stirred at rt overnight. The solvent was evaporated off and the residue triturated with ether. Yield 80 mg (88%), LCMS (Method J) RT 0.73 min (92% AP), m/z 284.2 (MH+), 1H NMR (300 MHz, DMSO-d6) δ ppm 7.30-7.45 (m, 5H), 7.27 (d, J=8.4, 2H), 6.97 (d, J=8.7, 2H), 5.09 (s, 2H), 4.09 (s, 1H), 3.44 (d, J=12.6, 2H), 3.32-3.29 (m, 1H), 3.08-3.20 (m, 1H), 2.95 (d, J=12.6, 1H), 2.48-2.58 (m, 1H), 1.82 (d, J=13.2, 1H).
