Reaction Steps

A solution of 4-amino-N′-hydroxy-N-(3-iodophenyl)-1,2,5-oxadiazole-3-carboximidamide (19 mg, 55 μmol), 2-propyn-1-ol (3.6 μL, 62 μmol), bis(triphenylphosphine)palladium(II) chloride (1 mg, 2 μmol), and copper (I) iodide (0.4 mg, 2 μmol) in N,N-dimethylformamide (0.5 mL) was treated with N,N-diethylamine (74 μL, 0.72 mmol) and heated in the microwave at 120° C. for 15 min. The reaction mixture was diluted with 1:1 acetonitrile/water (1.5 mL), filtered, and purified by preparative LCMS to give the desired product (4 mg, 28%). LCMS for C12H12N5O3 (M+H)+: m/z=274.0.
