Reaction Steps

A mixture of (3-bromo-imidazo[1,2-b]pyridazin-6-yl)-butyl-amine (100 mg, 0.37 mmol), 6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-isoquinoline (from part A, ˜1 mmol), K2CO3 (153 mg, 1.11 mmol) and dichlorobis(triphenylphosphine)palladium(II) (13 mg, 0.019 mmol) in MeCN/water (4 ml/1 ml) was heated in a microwave at 150° C. for 15 min. The water layer was removed and the reaction mixture was diluted with MeCN (3 ml) and filtered. The filtrate was subjected to preparative HPLC to give the titled compound (80.8 mg). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.03 (t, J=7.33 Hz, 3H) 1.53 (dq, J=14.97, 7.39 Hz, 2H) 1.74-1.81 (m, 2H) 3.48-3.54 (m, 2H) 4.58 (t, J=5.05 Hz, 1H) 6.54 (d, J=9.60 Hz, 1H) 7.68 (d, J=5.56 Hz, 1H) 7.75 (d, J=9.60 Hz, 1H) 8.01-8.05 (m, 2H) 8.25 (dd, J=8.72, 1.64 Hz, 1H) 8.55 (d, J=5.81 Hz, 1H) 8.86 (s, 1H) 9.25 (s, 1H). LRMS (ESI) m/z 318.2 [(M+H)]+, calc'd for C19H19N5: 317.40.
