Abstract-3-Bromo-7-methoxy-4-methylcoumarin and 3-bromo-4, 7-dimethylcoumarin 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.
