Reaction Steps

A mixture of 2-bromo-5-iodoimidazo[2,1-b][1,3,4]thiadiazole (0.127 g, 0.4 mmol, 1 eq), 3-acetamidobenzeneboronic acid (0.091 g, 1.3 equiv, 1.3 eq), dichlorobis(triphenylphosphine)palladium(II) (0.055 g, 02 eq) and 2M aq Na2CO3 (1.1 ml) in dioxane (5 mL) was heated at 110° C. for 3 h. The solvent was removed under reduced pressure, redissolved in ethylacetate and washed with water. The organic layer was dried over Na2SO4, filtered and concentrated. The residue (0.167 g) was used in the next step of the synthesis without further purification. HPLC-MS (10-95% B in 4 min at 0.5 mL+2 min 100% B, flow 0.8 mL/min, 50° C.): tR=4.03 min, [M+H]+ m/z 385.1.
