実験手順

6-(Spiro[4.5]dec-8-yloxy)-naphthalene-2-carboxylic acid methyl ester (0.312 g, 0.000922 mol) in tetrahydrofuran (9 mL, 0.1 mol) and 1.0 M of lithium tetrahydroaluminate in tetrahydrofuran (2.76 mL, 0.00276 mol) was added at 0° C. After stirring at rt for 2 h, quench with EtOAc, then Rochele's salt was added and stirred at rt for 1 h. Extraction with EtOAc, c/c give the product as a white solid (257.2 mg, 90%). LCMS Rt=2.21 min m/z=293.30 ([M−17], 100%).
