(R)-tert-butyl 3-((S)-1-(benzo[b]thiophen-2-yl)-1-hydroxy-5-methoxypentyl)piperidine-1-carboxylate (160 mg, 0.37 mmol) was dissolved in 1:1 2 N aq HCl solution/acetonitrile (50 mL). The mixture was stirred overnight at rt and neutralized with 5% aq NaOH. The acetonitrile was removed by evaporation. The aqueous residue was extracted by CH2Cl2 (2×40 mL). The combined organic layers were concentrated to afford (S)-1-(benzo[b]thiophen-2-yl)-5-methoxy-1-((R)-piperidin-3-yl)pentan-1-ol (102 mg, 83%) which was used without purification.
