    Abstract: A process for the preparation of 2-benzimidazole-carbamic acid alkyl and benzyl esters or the salts thereof, which comprises converting 2-amino-benzimidazoles with bases to their alkali metal or alkaline earth metal salts reacting these compounds with carbonic acid dialkyl or dibenzyl esters with exclusion of water, and optionally converting the 2-benzimidazole carbamate salts obtained to the free 2-benzimidazole-carbamic acid esters by acidification.
