Reaction Steps

3-Amino-4-((4-bromobenzyl)amino)phenol (7.8 g, 27 mmol) and cis-hexahydroisobenzofuran-1,3-dione (4.1 g, 27 mmol) were dissolved in acetonitrile (200 mL) and the mixture heated to 80° C. After 18 h, HCl (50 mL, 6 N) was added and the resulting mixture stirred at 60° C. for 16 h. The mixture was then cooled to RT and the pH was adjusted to ˜pH 7 with sat.NaHCO3. The aqueous was then extracted with EtOAc (3×200 mL). The combined organics were washed with water (200 mL), dried with Na2SO4, filtered and concentrated to dryness. The residue was purified by FCC to afford the title compound. 1H NMR (300 MHz, DMSO-d6) δ 12.13 (s, 1H), 8.93 (s, 1H), 7.47 (d, J=8.4, 2H), 7.06 (dd, J=8.6, 2.7, 3H), 6.89 (d, J=2.1, 1H), 6.60 (dd, J=8.6, 2.2, 1H), 5.52-5.26 (m, 2H), 3.63 (d, J=4.4, 1H), 2.70 (d, J=10.7, 1H), 2.55 (d, J=8.9, 1H), 1.81 (d, J=8.9, 2H), 1.61 (dd, J=32.5, 21.3, 3H), 1.34 (s, 2H).
