Prepared from N-(3-fluoro-4-(2-iodothieno[3,2-b]pyridin-7-yloxy)phenyl)-N-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide (Example 12, Step A, 50 mg, 0.0845 mmol) and 1-methyl-4-(prop-2-ynyl)piperazine (Example 17, Step A, 29.2 mg, 0.211 mmol) using the procedure described for Example 6, Step B. The crude was purified by preparative TLC (1 mm thickness, Rf=0.56), eluting with 10% MeOH (containing 7N NH3) in CHCl3. The product was obtained as a waxy solid (36 mg, 69%). HPLC: 100% purity (220 nm); LRMS (APCI+): 100% purity, 220 nm, m/z 602 (M+1) detected; 1H NMR (CDCl3, 400 MHz) δ 10.18 (s, 1H), 8.64 (s, 1H), 8.47 (d, J=5 Hz, 1H), 7.77 (m, 1H), 7.56 (s, 1H), 7.44 (m, 2H), 7.26 (m, 2H), 7.04 (m, 2H), 6.51 (d, J=5 Hz, 1H), 3.60 (s, 2H), 2.4-2.8 (m, 8H), 2.32 (s, 3H), 1.77 (m, 2H), 1.63 (m, 2H).
