N,N-diethylaniline effectively debrominated 3-bromo-4-methyl-7-methoxycoumarin and 3-bromo-4-bromomethyl-7-methoxycoumarin, at reflux.This and other reactions of the above-mentioned coumarins in refluxing N,N-diethylaniline provided supporting evidence for the mechanism of the fragmentation of simple 4-aryloxy-2-bromobut-2-enoates which occurred during their attempted Claisen rearrangement in refluxing N,N-diethylaniline.
