    • A process for the manufacture of furancarboxylic acid anilides of the general formula ##STR1## in which R.sub.1 represents an aryl group or an alkyl group, R.sub.2 and R.sub.3 each represent an alkyl group or hydrogen, by a ring-closure reaction of a .beta.-ketoester with an .alpha.-haloaldehyde or .alpha.-haloketone, in the presence of a stoichiometric amount of a halide-binding substance to form a furancarboxylic acid ester, and by subsequent anilidation, the reaction being performed in two stages, the ring-closure reaction being carried out in the presence of a mixture of alkaline earth metal carbonates and pyridine in a ratio of from 1000 to 5:1 Val, based on the hydrohalic acid liberated, at temperatures between 50.degree. and 100.degree. C.; and after separation in said second stage, the furancarboxylic ester is reacted while stirring with aniline in up to 20 times molecular excess, in the presence of equimolar amounts based on the furancarboxylic acid, of magnesium dianilide and/or aluminum trianilide in liquid phase or in suspension at temperatures between 20.degree. and 180.degree. C., under normal pressure. The furancarboxylic acid anilides have an outstanding pesticidal action.
