Procedure
A suspension of 3-(1-methylpiperid-4-yl)propionic acid hydrochloride (WO 9620173 A1, Example 1)(0.33 g, 0.00159 mole) in dry dichloromethane (10 ml) was treated with dimethylformamide (1 drop) and oxalyl chloride (0.416 ml, 0.605 g, 0.00477 mole) under an atmosphere of argon. After stirring for 3½ hours the mixture was concentrated in vacuo. The residue was dissolved in dry dichloromethane and concentrated in vacuo to give the title compound as a white solid.
