Abstract

than compensates for the somewhat lower yield obtained in the subsequent amination step. Although Eck and Marvel'insist on the use of dry reagents and take precautionary measures to prevent access of moisture to the bromination mixture, we have found that in the presence of a small amount of water the reaction proceeds smoothly with yields consistently above 950j0. This innovation leads to the preparation of a compound of sufficiently high purity ...
