SYNTHESIS AND STUDY OF THE PROPERTIES OF 4-SUBSTITUTED 3-AMINOMETHYLCOUMARINS

The aminomethylation of 4-hydroxycoumarin gave 3-pyrrolidinomethyl- and 3-piperidinomethyl-4-hydroxycoumarins, which were converted to 4-chloro derivatives by the action of phosphorus oxychloride.A number of 3-pyrrolidinomethyl- and 3-piperidinomethyl-4-aminocoumarins were synthesized by reaction of the 4-chloro derivatives with various amines, and some of their properties were studied.
