Procedure
20 ml of SOCl2 are added to a solution of 13.4 g of the furanoic acid prepared above in 70 ml of toluene. The mixture is refluxed for 3 h and the excess SOCl2 and the toluene are then distilled to give an oil, which is reacted at 5° C. with a solution of 100 ml of 1,2-dimethoxyethane saturated with ammonia. The precipitate is filtered off and washed with water and then with isopropyl alcohol to give 7 g of white crystals of amide.
