Reaction Steps
To a stirring solution of 2-(2-bromoethyl)-N-[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]-4,5-dihydro-2H-pyrimido[5′,4′:4,5]thieno[2,3-e]indazol-6-amine (100 mg, 0.16 mmol) in DMF (4 mL) were sequentially added 1-methyl-piperazine (0.023 mL, 0.24 mmol), sodium iodide (23.8 mg, 0.16 mmol), and sodium carbonate (33.6 mg, 0.32 mmol). The mixture was stirred at 60° C. for 4 h, after which time the contents were allowed to cool to rt and the solvent removed under reduced pressure. The crude product was purified via reverse phase HPLC to afford the desired product (32 mg, 34%) as a white solid. 1H-NMR (DMSO-d6) δ 8.58 (d, 1H), 8.40 (s, 1H), 8.36 (s, 1H), 7.93 (s, 1H), 7.83 (dd, 1H), 7.78 (s, 1H), 7.47-7.59 (m, 2H), 7.31 (dd, 1H), 7.19 (d, 1H), 5.25 (s, 2H), 4.12 (t, 2H), 3.35 (t, 2H), 2.85 (t, 2H), 2.63 (t, 2H), 2.35-2.45 (br s, 4H), 2.22-2.32 (br s, 4H), 2.12 (s, 3H); LCMS RT=2.18 min; [M+H]+=587.4.
