실험 절차

Add several drops of HCl (5M) to a stirred solution of crude [2-(2-hydroxymethyl-phenyl)-6-methoxy-naphthalen-1-yl]-[4-(2-piperidin-1-yl-ethoxy)-phenyl]-methanol in THF (5 mL) and water (0.5 mL). Stir at r.t. for 24 h. Quench with aq. NaHCO3 and dilute with CH2Cl2. Wash the organic phase with water and brine, dry over MgSO4, filter and concentrate. Purify the crude product by flash chromatography (0-5% (2M NH3/MeOH) in CH2Cl2) to yield 1-{2-[4-(8-methoxy-11,13-dihydro-12-oxa-benzo[3,4]cyclohepta[1,2-a]naphthalen-11-yl)-phenoxy]-ethyl}-piperidine (105 mg, 64%).
