Versuchsvorschrift

To a solution of 5a (32 mg, 0.0502 mmol) in H2O (9 mL) at room temperature was added 10% Pd/C (13 mg) under Ar (g). The reaction mixture was placed under hydrogenation apparatus for 24 h. The resulting mixture was filtered via celite bed and washed thoroughly with H2O. The filtrate was concentrated to provide 6a (30 mg, 93%) as a yellowish solid. 1H NMR (D2O, 300 MHz) δ 2.43-4.25 (m, 22H), 7.21 (s, 4H).
