Participants

Reaction Steps

Using a procedure similar to Example 32, from 3-(5-bromo-2-methyl-thiophen-3-yl)-8-(1-ethyl-propyl)-2,6-dimethyl-imidazo[1,2-b]pyridazine (0.20 g, 0.51 mmol) and PdCl2(dppf) (0.019 g, 0.025 mmol) and 0.5 M solution of phenylzinc iodide in THF (2.0 mL, 1.02 mmol). The residue is purified by column chromatography (0-10% EtOAc/hexane gradient) and is chromatographed (50×250 C18 Symmetry column, 30-70% water: 0.1% TFA/ACN: 0.1% TFA gradient) furnish the title compound (0.081 g, 0.21 mmol, 41%). 1H NMR (CDCl3), δ 0.90 (t, J=7.5 Hz, 6H), 1.75-1.94 (m, 4H), 2.40 (s, 3H), 2.48 (s, 3H), 2.52 (s, 3H), 3.32-3.41 (m, 1H), 6.66 (s, 1H), 7.23-7.30 (m, 1H), 7.32 (s, 1H), 7.34-7.41 (m, 2H), 7.57-7.63 (m, 2H). LC/MS (m/z): calcd. for C24H27N3S (M+H)+: 390.2; found: 390.2.
