Reaction Steps
A suspention of (±)-(2R,4R)-tert-butyl 4-acetoxy-2-(4-fluorophenyl)piperidine-1-carboxylate (150 mg, 0.40 mmol) and potassium carbonate (1.0 g) in methanol:water 10:1 (11 mL) was stirred for 1 hour then diluted with ethyl acetate (40 mL) and washed with water (25 mL) and brine (25 mL). The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated to give (±)-(2R,4R)-tert-butyl 2-(4-fluorophenyl)-4-hydroxypiperidine-1-carboxylate (117 mg, 99% yield). 1H NMR (400 MHz, d6-DMSO): 7.17 (m, 4H), 5.34 (br d, 1H), 4.73 (d, 1H), 4.34 (br d, 1H), 3.41 (m, 1H), 2.67 (m, 1H), 2.42 (br d, 1H), 1.57 (m, 1H), 1.38 (s, 9H).
