Reaction Steps

By using 1-(3-diisopropylaminopropyl)isatin and semicarbazide hydrochloride, a method analogous to that described in Example 4 was carried out to obtain (E)-1-(3-diisopropylaminopropyl)isatin 3-semicarbazone having a melting point of 173°-175° C. (yield: 66.6%, recrystallizing solvent: methanol-benzene).
