実験手順
When in the procedure of Example 17, Step (2), 4-[(2-nitro-benzenesulfonylamino)-methyl]-benzoic acid tert-butyl ester was replaced with N-(4-methoxy-benzyl)-2-nitro-benzenesulfonamide, the title compound 2-amino-N-(4-methoxy-benzyl)-benzenesulfonamide was obtained as a thick oil. 1H-NMR (CDCl3); δ 7.71 (dd, 1H), 7.07 (d, 2H), 6.78 (m, 4H), 4.93 (bt, 1H), 4.82 (bs, 2H), 3.95 (d, 2H), and 3.75 (s, 3H). MS: M+−1=291.0 Da Step (3): Synthesis of 2-Amino-5-bromo-N-(4-methoxy-benzyl)-benzenesulfonamide
