To a 25 mL round-bottomed flask was added N1-((1-ethyl-1H-indazol-3-yl)methyl)-4-(quinolin-2-ylmethoxy)benzene-1,2-diamine (37 mg, 0.09 mmol), cis-6,6-dimethyl-3-oxa-bicyclo[3.1.0]hexane-2,4-dione (12 mg, 0.09 mmol) and acetonitrile (0.8 mL). The solution was heated to 80° C. for 4 h. To this solution was added HCl (0.4 mL, 6 N) and the mixture heated to 90° C. for 15 h. The mixture was cooled to RT over 30 minutes. The resulting solids were filtered off and the liquid purified by reverse phase HPLC to afford the title compound. MS (ESI): mass calcd. for C33H31N5O3, 545.24; m/z found, 546.2 [M+H]+. 1H NMR (500 MHz, CDCl3) δ 8.57 (d, J=8.5, 1H), 8.37 (d, J=8.7, 1H), 7.99 (d, J=8.2, 1H), 7.95-7.89 (m, 2H), 7.76-7.72 (m, 1H), 7.55 (d, J=9.1, 1H), 7.42-7.37 (m, 4H), 7.25-7.22 (m, 1H), 7.16-7.11 (m, 1H), 5.72 (s, 2H), 5.66 (s, 2H), 4.36 (q, J=7.3, 2H), 2.50 (s, 2H), 1.45 (t, J=7.3, 3H), 1.29 (s, 3H), 1.10 (s, 3H).
