Reaction Steps

A microwave vessel was charged with 3-bromo-7-phenylimidazo[1,2-a]pyridine (6-1, 0.050 g, 0.183 mmol), thiazole (0.065 ml, 0.92 mmol), tetrakis(triphenylphosphine)palladium(0) (0.011 g, 0.10 mmol) and KOAc (0.054 g, 0.55 mmol). N,N-dimethylacetamide, 1.5 ml, was added and the reaction was placed in the microwave reactor. The reaction was heated to 200° C. for 10 min. The reaction was diluted with water, and extracted 3× with DCM. The extracts were dried over Na2SO4, filtered and concentrated. The resulting residue was dissolved in DMSO and purified by reverse phase preparative HPLC. The resulting oil was triturated with ether, resulting in the rapid crystallization to a white solid. The solid was filtered and washed with ether. Afforded the pure title compound. 1H NMR (CDCl3) δ 9.11 (s, 1H), 8.47 (s, 1H), 8.37 (d, 1H, J=7.4 Hz), 8.20 (s, 1H), 8.00 (s, 1H), 7.73 (d, 2H, J=7.3 Hz), 7.57–7.52 (m, 4H). LCMS m/z (M+1) Calc: 278.1, found 278.1.
