Hexachloroplatinic acid (I) was reduced to potassium tetrachloroplatinate (II) using hydrazine. Treatment of (II) with KI produced the tetraiodoplatinate (III), which was converted to the diamino compound (IV) by reaction with isopropylamine. Conversion to the dinitrate (V) was then effected by iodide ion exchange with silver nitrate. Diels-Alder condensation of maleic anhydride (VI) with furan (VII) furnished adduct (VIII), which was further hydrogenated to (IX) using Pd/C. Then, basic hydrolysis of the cyclic anhydride in the presence of the platinum complex (V) afforded the title compound.
