Procedure
By using isatin and 3-diisopropylaminopropyl chloride hydrochloride, a method analogous to that described in Reference Example 1 was carried out, and the reaction product was purified with silica gel column chromatography (eluent: chloroform/methanol=50/1) and then recrystallized from hexane to obtain 1-(3-diisopropylaminopropyl)isatin having a melting point of 49°-50° C. (yield: 72.9%).
