Abstract

Novel prepn. of anthelmintic methyl (5-propyl-sulphenyl-benz-imidazole-2-yl)-carbamate of general formula (I), by the amino-imino -methane-sulphonic acid redn. of cpd. of general formula (II) in the presence of alkali-metal-hydroxide to cpd. (III). The alkali salt of this mercaptan reacts with n-propyl-bromide. The reducing agent is prepd. from thiourea and hydrogen-peroxide in the presence of water during 25-360 mins. pref. 25-60 mins. so that the temp. of the agent should be 20-70 deg.C at completion.
