Reaction Steps
3 mL (19.86 mmol) of 3-bromobutan-2-one are added to a mixture, stirred at 20° C., of 1.5 g (8.67 mmol) of 2-amino-4-bromopyridine and 1.45 g (17.34 mmol) of sodium hydrogen carbonate in 50 mL of ethanol. The mixture is stirred at reflux for 12 hours and then concentrated under reduced pressure. The mixture obtained is taken up in 20 mL of water. The pH of the solution is basified by successive addition of potassium carbonate. A precipitate is collected by filtration, and is washed with water and then dried under reduced pressure. 0.79 g of the expected product is thus isolated, and is used without further purification in the rest of the synthesis.
