Reaction Steps

By using 1-(2-diisopropylaminoethyl)-5-fluoroisatin and semicarbazide hydrochloride, a method analogous to that described in Example 6 was carried out to obtain (E)-1-(2-diisopropylaminoethyl)-5-fluoroisatin 3-semicarbazone having a melting point of 158°-160° C. (yield: 86.5%, recrystallizing solvent: chloroform-hexane).
