Reaction Steps

3.0 g of 5-bromopyridin-2-ylamine in 5.8 ml of ethyl 2-bromoacetate are placed in a round-bottomed flask and stirred at ambient temperature for 48 h. A precipitate forms, and is recovered by filtration, washed with diethyl ether and oven-dried under reduced pressure. The solid is then taken up in 50 ml of ethanol, and 2.18 g of sodium hydrogencarbonate are added thereto. The reaction mixture is heated at the reflux of the solvent for 5 h, cooled to ambient temperature, and then concentrated under reduced pressure. The residue obtained is taken up between water and dichloromethane and the organic phase is separated, dried and concentrated under reduced pressure. 1.46 g of compound, used as it is in the subsequent stages, are obtained.
