Procedimiento

5.0 g of 2-amino-5-iodopyridine, 5.3 g of 2-bromo-1-(4-chlorophenyl)ethanone and 2.67 g of sodium hydrogen carbonate in 150 ml of n-propanol are placed in a round-bottomed flask. The mixture is heated at 80° C. for 40 h and left to cool, and 700 ml of water are added. The precipitate is recovered by filtration, washed with water and dried under reduced pressure. 5.51 g of compound are obtained.
