Reaction Conditions

Reaction Steps

A suspension of 2.94 g of isatin, 4.20 g of 2-diisopropylaminoethyl chloride hydrochloride, and 3.17 g of anhydrous potassium carbonate in 50 ml of toluene was stirred for 4 hours at 90° C. After cooling, the reaction mixture was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was recrystallized from hexane to obtain 4.93 g of 1-(2-diisopropylaminoethyl)isatin. The chemical properties of this product are identical with those of the product obtained by Reference Example 1.
