Reaction Steps
A suspension of 10.00 g of 1-(2-diisopropylaminoethyl)isatin and 4.88 g of semicarbazide hydrochloride in 350 ml of a mixture of ethanol and water (2.5:1) was stirred for 2 hours at room temperature. The suspension was warmed to make a solution, and then 44.0 ml of a 1N-aqueous sodium hydroxide solution was added dropwise to the solution. The precipitates were collected by filtration and washed with water to obtain 10.56 g of (E)-1-(2-diisopropylaminoethyl)isatin 3-semicarbazone. The chemical properties of this product were identical with those of the product obtained by Examle 1.
