Reaction Steps

To a stirred solution of 2-(1-benzylpyrrolidin-3-yl)-5-methylpyridine (200 mg, 0.79 mmol) in dry CH2Cl2 (3 mL) were added Et3N (80 mg, 0.79 mmol) and 1-chloroethyl carbonochloridate (225 mg, 1.6 mmol) at 0° C. The mixture was stirred at 0° C. for 2 h. The reaction mixture was concentrated under vacuum and dissolved in CH2Cl2 (5 mL). The organic solution was washed with water (20 mL×3), and the combined aqueous layers were concentrated to give crude 5-methyl-2-(pyrrolidin-3-yl)pyridine (150 mg, 82%) as a solid, which was used for next step without purification.
