Reaction Steps

Aryl iodide 35 (Example 290, 50 mg, 0.11 mmol) and 3-fluoro-2-hydroxypyridine (38 mg, 0.33 mmol) were dissolved in 1.0 mL dry dioxane and 0.3 mL dry DMSO in a sealed tube. To it were added N,N′-dimethylethylenediamine (8 μL, 0.066 mmol), CuI (11 mg, 0.055 mmol) and K3PO4 (48 mg, 0.22 mmol) in order. The mixture was stirred and heated in 120° C. bath for overnight. 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 C19H13ClFN5O2S as (M+H)+ 430.0, 432.0.
