<p>The process comprises reaction of a compound of formula: with alkyl isothiocyanate of formula R1-N=C=S, where R1 is C 1-4 alkyl. The reaction in aqueous medium at 25-100 degrees C, is followed by treatment with methyl iodide in organic medium at 25-100 degrees C. - Final reaction with nitromethane in acetic acid and pyridin yields N 2-(((5((dimethyl amino)methyl)-2 furanyl)methyl)thio) ethyl)-N'-alkyl-2-nitro-1,1 -ethenodiamine of formula.</p> |
