Reaction Steps

Ethyl 2-benzyl-3-((S)-1-(4-ethylthiazol-2-yl)-2-(4-nitrophenyl)ethylamino)-3-oxopropanoate is dissolved in toluene (5 mL) and heated to reflux. Potassium carbonate (80 mg) and acetamide oxime (43 mg) are added and treated with 80 mg potassium carbonate and 43 mg acetamide oxime at reflux. The reaction mixture is cooled to room temperature, filtered and concentrated. The residue is chromatographed over silica to afford 0.221 g (94%) of the desired product as a yellow oil.
