実験手順
A solution of 2-carboxymethyl-5-methoxy-phenyl-oxy-(3-nitrobenzene) (57 g, 0.187 mol) and 10% Pd/C (11 g) was hydrogenated in MeOH (1000 mL) at 50 psi for 2 h. The solution was filtered through Celite® and the filtrate was concentrated. Flash chromatography (silica gel, 20% EtOAc/Hexane) yielded the title compound (49.3 g, 96%): MS (ES) m/e 274.1 (M+H)+.
