Reaction Steps

Following the representative procedure GENERAL METHOD 1-6 for Suzuki cross-coupling, 3-fluoro-5-hydroxy-4-(6-((2,2,6,6-tetramethylpiperidin-4-yl)oxy)pyridazin-3-yl)phenyl trifluoromethanesulfonate and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate were reacted and the crude product was purified via reverse phase preparative HPLC (10% CH3CN to 30% in H2O). After salt formation, the hydrochloride salt of 3-fluoro-5-(1H-pyrazol-4-yl)-2-(6-((2,2,6,6-tetramethylpiperidin-4-yl)oxy)pyridazin-3-yl)phenol hydrate was afforded as a yellow solid (49 mg, 25%). LCMS Rt=0.49 min; [M+H]: 412.3; 1H NMR (400 MHz, MeOD) δ 8.51 (d, J=9.5 Hz, 1H), 8.26 (s, 2H), 7.87 (d, J=9.5 Hz, 1H), 7.21 (dd, J=12.0, 1.5 Hz, 1H), 7.16 (s, 1H), 5.77 (tt, J=10.5, 4.0 Hz, 1H), 2.52 (dd, J=14.0, 4.0 Hz, 2H), 1.93 (dd, J=14.0, 10.5 Hz, 2H), 1.64 (s, 6H), 1.59 (s, 6H).
