Reaction Steps

(Z)-N-(2-Phenylethyl)-2-(2-dimethylaminomethylidenaminothiazol-4-yl)-2-methoxyiminoacetamide (130 mg, 0.36 mmol) was dissolved in 4 ml of methanol, followed by the addition of 1 ml of 2N hydrochloric acid. The mixture so obtained was stirred at 60 ml for 3 hours and 30 minutes. The reaction mixture was then added with 20 ml of a saturated aqueous solution of sodium hydrogencarbonate and 20 ml of ethyl acetate. The resulting mixture was then allowed to separate into an organic phase and an aqueous phase. The aqueous phase was further extracted twice with 10 ml portions of ethyl acetate. All the organic phases were combined, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure, whereby 107 mg of the title compound were obtained (yield: 97.5%).
