Procedure

The title compound (9.0 mg, 17%, 88% purity) was synthesized from 1-(3-(1-(1-methyl-1H-indazol-5-yl)ethyl)imidazo[1,2-b]pyridazin-6-yl)ethanone (40.0 mg, 0.13 mmol) and 2-(aminooxy)ethanol hydrochloride (19.31 mg, 0.25 mmol) using the same procedure as described in the synthesis of example 13. 1H-NMR (400 MHz, DMSO-d6) δ ppm 7.94 (d, 1H), 7.85 (s, 1H), 7.79 (s, 1H), 7.66 (s, 1H), 7.85 (d, 1H), 7.52 (d, 1H), 7.37 (dd, 1H), 4.72 (t, 2H), 4.21 (t, 2H), 3.97 (s, 3H), 3.66 (q, 1H), 2.20 (s, 3H), 1.78 (d, 3H). LCMS (method A): [MH]+=379, tR=5.25 min.
