Abstract
Bromoacetamides of the formula ArCONHCH(Br)CONH.sub.2 are obtained by addition to bromine of a solution of ArCONHCH.sub.2 CN in a saturated aliphatic carboxylic acid preferably glacial acetic or propionic acid. This is an improvement in a process described in European Patent Specification No. 0059536 in which the bromine is added to a solution of the cyanomethylbenzamide, enabling consistently high yields (e.g. 75 to 90%) to be obtained.
