実験手順
A mixture of 4-chloro[1,5]naphthyridin-3-amine (2.0 g, 11 mmol) and 4-chlorobutyryl chloride (4.7 g, 33 mmol) in 1,2-dichloroethane (75 mL) was heated at reflux for 20 hours. The reaction mixture was then concentrated under reduced pressure and the residue washed with two 25 mL portions of hexane. The solid was then taken up in methanol (35 mL), 1.0 mL of 10% solution of sodium hydroxide in water was added, and the solution was stirred at room temperature for 4 hours. The reaction mixture was then concentrated under reduced pressure to provide 4-chloro-N-(4-chloro[1,5]naphthyridin-3-yl)butanamide which was used directly in the next step without further purification.
