A solution of N-{4-[4-(3-bromo-4-fluorophenyl)-5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl]-1,2,5-oxadiazol-3-yl}-2,2,2-trifluoroacetamide (50 mg, 0.11 mmol), nicotinyl alcohol (14 μL, 0.15 mmol), and triphenylphosphine (42 mg, 0.16 mmol) in tetrahydrofuran (0.35 mL) at 0° C. was treated with diisopropyl azodicarboxylate (34 μL, 0.17 mmol). The reaction mixture was stirred at 25° C. for 16 h and purified by preparative LCMS to give the desired product (4 mg, 6%). LCMS for C6H11BrFN6O3 (M+H)+: m/z=432.9, 434.9.
