Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By using 5-bromo-1-(2-diisopropylaminoethyl)isatin and 4-cyclohexylsemicarbazide, a method analogous to that described in Example 16 was carried out to obtain (E)-5-bromo-1-(2-diisopropylaminoethyl)isatin 3-(4-cyclohexylsemicarbazone) having a melting point of 155°-156° C. (yield: 89.9%, recrystallizing solvent: chloroform-hexane).
