Versuchsvorschrift

A solution of N′-hydroxy-N-{6-[({[(Z)-(4-methyl-5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)(phenyl)methylene]amino}oxy)methyl]pyridin-2-yl}ethanimidamide (150 mg, 0.392 mmol, 1 eq), iodomethylcyclopropane (0.069 ml, 0.588 mmol, 1.5 eq) and cesium carbonate (191 mg, 0.588 mmol, 1.5 eq) in DMF (3 ml) was stirred at 80° C. for 7 h and overnight at room temperature. Iodomethylcyclopropane (0.069 ml, 0.588 mmol, 1.5 eq), cesium carbonate (191 mg, 0.588 mmol, 1.5 eq) and potassium iodide (0.1 eq) were then added and the mixture was stirred at 60° C. for 8 h. Water was added and the mixture was extracted with ethyl acetate. The organics were combined, dried over MgSO4 and evaporated. The residue was purified by chromatography on silica gel to afford N′-(cyclopropylmethoxy)-N-{6-[({[(Z)-(4-methyl-5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)(phenyl)methylene]amino}oxy)methyl]pyridin-2-yl}ethanimidamide (20 mg, 10% yield) as a transparent oil.
