Reaction Steps
To a solution of 1.37 g of 1-(2-diisopropylaminoethyl)isatin and 0.86 g of 4-phenylsemicarbazide in ml of a mixture of ethanol and water (2:1) was added 3 drops of acetic acid, and the mixture was stirred for 3 hours at 70° C. The yellow precipitates were collected by filtration, and recrystallized from ethanol to obtain 1.24 g of (E)-1-(2-diisopropylaminoethyl)isatin 3-(4-phenylsemicarbazone) having a melting point of 157°-159° C.
