실험 절차

To a stirred solution of (R)-ethyl 3-(3′,4′-dihydro-2′H-spiro[[1,3]dioxolane-2,1′-naphthalen]-3′-yl)propanoate (2.3 g, 7.92 mmol) in THF (10 mL) and water (1 mL) in round bottom flask. LiOH (1.328 g, 55.4 mmol) was added and reaction mixture was stirred at 25° C. for 2 h. Reaction mixture was concentrated and acidified with dilute HCl, stirred for 1 h at RT. Extracted with ethyl acetate (2×30 mL), dried over sodium sulphate, concentrated to get crude title compound (1.6 g, 93%); m/z 262.7
