実験手順
A mixture of 1.0 g (1.91 mmol) 3-(2-benzyloxy-4-nitro-benzenesulfonylamino)-N-methyl-succinamic acid tert-butyl ester from Route D, 0.2 g 20% Pd/C, and 75 mL of a 1:1 mixture of THF:MeOH was shaken under 50 psi H2 gas for 4.5 h. TLC analysis showed reaction complete. The reaction was filtered to remove catalyst and the solvent evaporated under reduced pressure to give 3-(4-amino-2-hydroxy-benzenesulfonylamino)-N-methyl-succinamic acid tert-butyl ester 0.78 g (100%) as a light yellow foam. MS (APCI) m/z 402 (M−1).
