Procedure

Into a 1-neck round-bottom flask was added tert-butyl (3-aminophenyl)carbamate (1.0 g, 4.8 mmol) and tetrahydrofuran (20 mL) and triethylamine (1.0 mL, 7.2 mmol). The mixture was cooled in an ice bath and (3-nitrophenyl)methanesulfonyl chloride (1.1 g, 4.8 mmol) was slowly added. The resultant mixture was warmed to rt. The solvent was removed under vacuum and EtOAc and water added. The aqueous phase was extracted again with EtOAc. The organic layers were combined, dried over Na2SO4 and the solvent removed under vacuum to give the desired product (1.94 g, 99%). LCMS for C18H21N3O6S (M-Boc+H)+: m/z=308.0. 1H NMR (400 MHz, DMSO-d6): δ 9.84 (s, 1H), 9.37 (s, 1H), 8.98 (s, 1H), 8.19 (ddd, J=8.1, 2.3, 1.1 Hz, 1H), 8.11 (t, J=1.9 Hz, 1H), 7.71 (dt, J=7.7, 1.3 Hz, 1H), 7.63 (t, J=7.9 Hz, 1H), 7.44 (t, J=2.0 Hz, 1H), 7.15 (t, J=8.0 Hz, 1H), 7.10 (m, 1H), 6.81 (t, J=8.0 Hz, 1H), 6.78 (br, 1H), 6.75 (ddd, J=7.4, 2.2, 1.6 Hz, 1H), 1.46 (s, 9H).
