Procedure
3-Fluoroazetidine-3-carboxylic acid hydrochloride (0.10 g, 8.4 mmol) was dissolved in methanol (2 mL) and cooled to 5° C. Thionyl chloride (0.05 g, 4.2 mmol) was added dropwise. The reaction mixture was heated at 65° C. overnight and concentrated under reduced pressure to afford methyl 3-fluoroazetidine-3-carboxylate hydrochloride. The product was used in the next step without further purification.
