Reaction Steps

Aryl bromide (Example 1, 100 mg, 0.25 mmol) and 2-hydroxypyridine (95 mg, 1.0 mmol) were dissolved in 1.5 mL dry dioxane and 0.5 mL dry DMSO in a sealed tube. To it were added N,N′-dimethylethylenediamine (27 μL, 0.25 mmol), CuI (95 mg, 0.125 mmol) and K3PO4 (106 mg, 0.5 mmol) in order. The mixture was stirred and heated in 120° C. bath till all the bromide starting material had been consumed (3 hrs, monitored by analytical HPLC). The mixture was filtered and directly subjected to reverse phase preparative HPLC to isolate the title compound as a white powder after lyophilization. MS found for C20H16ClN3O3S as (M+H)+ 414.1, 416.1
