実験手順
NaOH 5M (7.7 ml, 38.6 mmol, 2 eq) is added to a stirred solution of 3-[2-(methoxycarbonyl)phenyl]pyrrolidine-1-carboxylate a1-2 (5.9 g, 19.3 mmol, 1 eq) in MeOH (50 ml) at 65° C. The reaction mixture is stirred overnight at 65° C., then evaporated under vacuum and water (40 ml) is added. The resulting mixture is extracted with ethyl acetate/ethanol (100 ml/10 ml) and again with ethyl acetate (100 ml). The combined organic layers are dried over MgSO4, filtered off and evaporated under vacuum to afford 5.5 g of pure 2-[1-(tert-butoxycarbonyl)pyrrolidin-3-yl]benzoic acid a1-3.
