Reaction Steps

To a solution of 2-(6-methoxy-[1,5]naphthyridin-4-yl)-4,5,6,7-tetrahydro-2H-indazol-5-ylamine (160 mg, 0.54 mmol) in DMF (3 mL) was added 1-(2-bromo-ethoxy)-3,5-difluoro-benzene (154 mg, 0.65 mmol), Cs2CO3 (267 mg, 0.82 mmol) and catalytic NaI (25 mg, 0.002 mmol). After 48 h at 50° C., the mixture was concentrated, and the residue was dissolved in EtOAc, washed with H2O, dried (MgSO4), and concentrated. The resulting residue was purified by basic reverse phase HPLC to provide 53.8 mg (29%) of the title compound as a brown gum. MS (ESI): exact mass calculated for C25H24F2N4O2, 450.48; m/z found, 451.2 [M+H]+. 1H NMR (500 MHz, CD3OD): 8.74 (d, J=4.9, 1H), 8.01 (d, J=9.2, 1H), 7.95 (s, 1H), 7.71 (d, J=2.7 1H), 7.50-7.48 (m, 2H), 6.61 (dd, J=9.2, 2.1, 2H), 6.52 (tt, J=9.2, 2.2, 1H), 4.14 (t, J=5.3, 2H), 3.90 (s, 3H), 3.13-3.09 (m, 4H), 3.00-2.96 (m, 1H), 2.83 (ddd, J=16.6, 10.7, 5.8, 1H), 2.54-2.51 (m, 1H), 2.26-2.23 (m, 1H), 1.85-1.77 (m, 1H).
