Reaction Steps

To a solution of 2-phenylethyl (4-{[({(1Z,2Z)-2-[ethyl(hydroxy)amino]-2-imino-1-phenylethylidene}amino)oxy]methyl}-1,3-thiazol-2-yl)carbamate (160 mg, 71% purity, 0.24 mmol, 1 eq.) in acetonitrile (3 ml), was added 1,1′-carbonyldiimidazole (555 mg, 0.342 mmol, 1.4 eq.). After stirring at 80° C. for 6 hour, the reaction was quenched by addition of water and extracted with EtOAc. The organics were combined, dried over MgSO4 and concentrated. The residue was purified by chromatography on silica gel to give 3-[(Z)-{[(2-amino-1,3-thiazol-4-yl)methoxy]imino}(phenyl)methyl]-2-ethyl-1,2,4-oxadiazol-5(2H)-one (70 mg, 55% yield).
