Reaction Steps

A mixture of 96B [2,2,6,6-tetramethyl-1-((1-(3-phenoxyphenyl)-2-oxabicyclo[2.2.2]octan-4-yl)oxy)piperidin-4-ol] (140 mg, 0.310 mmol), activated zinc dust (203 mg, 3.10 mmol), and HOAc (3.55 mL, 62.0 mmol) in THF (1 mL)/water (0.5 mL) was stirred at rt for 3 days, then was filtered. The filtrate was dissolved in EtOAc (5 mL) and washed with water. The organic layer was dried (MgSO4) and concentrated in vacuo. The crude product was chromatographed [SiO2; continuous gradient of EtOAc/hexane (0% to 50% over 10 min)] to give the title compound (62 mg, 0.209 mmol, 68% yield) as a clear oil. [M+Na]+=319.1; 1H NMR (CDCl3) δ: 7.38-7.27 (m, 3H), 7.20-7.09 (m, 3H), 7.06-6.99 (m, 2H), 6.92-6.86 (m, 1H), 3.88 (t, J=1.6 Hz, 2H), 2.24-2.12 (m, 4H), 2.01-1.84 (m, 4H), 1.70 (s, 1H).
