合成路线1
Pentafluorophenylalanine methyl ester (I) was treated with phosgene and pyridine to afford isocyanate (II), which was condensed with 5-aminothiadiazole-2-thione (III) to provide urea (IV). Then, displacement of the ester function of (IV) with 1-(2-pyridyl)piperazine (V) furnished the title amide.
