Reaction Steps
To a solution of ethyl 3-phenyl-3-(1-tert-butylcarbonyloxypiperidin-4-yl)propionoate (5.3 g, 14.6 mmol) in THF (100 mL) was added lithium aluminium hydride (14.6 mL, 1M, 14.6 mmol) dropwise over 20 min. The resulting mixture was stirred at 0° C. for 1 h. 2M aqueous sodium hydroxide (20 mL) was added dropwise. The mixture was filtered through Celite®, washing with ethyl acetate (3×25 mL). The filtrate and washings were combined and evaporated. The residue was dissolved in ethyl acetate (100 mL) and the resulting solution washed with water (3×50 mL), dried and evaporated to give the sub-titled compound (4.6 g); NMR: 0.9–1 (m, 2H) 1.25 (m, 1H) 1.35 (s, 9H) 1.5–2 (m, 5H) 2.6 (m, 2H) 3.1 (m, 2H) 3.8-4 (m, 2H) 4.2 (t, 1H).
