Combine N,N′-diphenethyl-2-(t-butoxycarbonylamino)malonamide (0.571 g, 1.35 mmol) and dichloromethane (10 mL). Add trifluoroacetic acid (1.8 mL). After 2.5 hours, evaporate in vacuo to give a residue. Add hexanes and carbon tetrachloride to co-evaporate residual trifluoroacetic acid and evaporate in vacuo to give the title compound (100%).
