Procedure

Glutaric anhydride (1.14 g, 10.0 mmol) was added to a solution of 5-amino-2-methoxypyridine (1.24 g, 10.0 mmol) in dichloromethane (25 mL). After standing for 1 hour at room temperature, thionyl chloride (5.95 g, 50.0 mmol) was added, followed by heating to reflux for 0.5 hour. The solvent and excess thionyl chloride were evaporated in vacuo, yielding 4-(6-methoxy-pyridin-3-ylcarbamoyl)-butyryl chloride, which was used without further purification.
