Abstract
Process for the preparation of 5-nitrofuryl derivatives of the general formula i ** (see formula) ** In which R1 means an unsubstituted alkyl group, containing 1 to 5 carbon atoms; or a carbalkoxy group containing in the alkyl part of 1 to 5 carbon atoms, and R2 means hydrogen; an alkyl group containing from 1 to 5 carbon atoms, which may be unsubstituted or in which one, several or all hydrogen atoms may be replaced by chlorine or bromine atoms; or a cycloalkyl group containing in the carbocyclic ring of 5 to 7 carbon atoms; an aralkyl group containing up to 12 carbon atoms; or an alkenyl group containing 2 to 4 carbon atoms, Characterized in that a compound of the general formula ii is reacted ** (see formula) ** With an acid anhydride (r2co) 2o, wherein r1 and r2 have the significance indicated under formula i, in the presence of a non-dehydrating proton donor catalyst, and the intermediate product obtained of general formula iii ** (see formula) ** It is then allowed to react after isolated or without preceding isolate, with ammonia or with a compound, which liberates ammonia in-situ under the reaction conditions, to form compounds of the general formula i.
