Abstract

3-Bromo-7-methoxy-4-methylcoumarin and 3-bromo-4,7-dimethyl-coumarin give a mixture of the corresponding 3-aminocoumarins and 4-aminomethylcoumarins upon the reaction with a number of secondary amines. In addition, the reaction of 7-methoxy- and 7-methyl-4-bromomethylcoumarins with secondary diamines affords the corresponding N,N`-dicoumarinmethyldiamine.
