Reaction Steps

A mixture of [1-(3-bromo-imidazo[1,2-b]pyridazin-6-yl)-pyrrolidin-3-yl]-methyl-carbamic acid tert-butyl ester (100 mg, 0.25 mmol), 4-pyridinylboronic acid (40 mg, 0.33 mmol), K2CO3 (104 mg, 0.75 mmol) and dichlorobis(triphenylphosphine)palladium(II) (8.8 mg, 0.013 mmol) in MeCN/water (3.2 ml/0.8 ml) was heated in a microwave at 150° C. for 15 min. The water layer was removed and the organic layer was diluted with MeCN and filtered. The filtrate was subjected to preparative HPLC to give the titled compound (25.3 mg). 1H NMR (400 MHz, METHANOL-d4) δ ppm 1.50-1.55 (m, 9H) 2.22-2.32 (m, 2H) 2.89 (s, 3H) 3.46-3.57 (m, 2H) 3.72-3.80 (m, 2H) 4.91 (t, J=7.61 Hz, 1H) 6.95 (d, J=9.92 Hz, 1H) 7.77 (d, J=9.70 Hz, 1H) 8.11 (s, 1H) 8.23-8.27 (m, 2H) 8.53-8.58 (m, 2H). LRMS (ESI) m/z 395.2 [(M+H)]+, calc'd for C21H26N6O2: 394.48.
