Procedure
The hydrochloride salt of (±)-N-methylnipecotic acid (1.0 g) was suspended in dichloromethane (25 ml) and stirred at room temperature for 2 h with oxalyl chloride (0.58 ml) and DMF (1 drop). The solvent was then evaporated to yield the hydrochloride salt of N-methylnipecotyl chloride as a pale yellow solid.
