Participants

Reaction Steps

50 mg N-[5-(4,4-Dimethyl-2,5-dioxo-3-pyridin-4-ylmethyl-imidazolidin-1-yl)-2-trifluoromethoxy-phenyl]-2-chloro-acetamide (raw material, as described above) owere dissolved in 2 ml morpholine and heated for 1 h to 50° C. Subsequently, the mixture was poured on ice and extracted with ethylacetate. The combined organic phases were evaporated to dryness and the residue was purified by flash chromoatography (Silica gel, methylene chloride:methanol=1.98:22.95:5) Yield: 20 mg
