Chloroacetyl chloride (632 μl, 7.94 mmol) was added dropwise to a solution of (3R)-3-fluoropyrrolidine (1 g, 7.94 mmol) and triethylamine (2.2 mL, 15.9 mmol) in CH2Cl2 (20 mL) at 5° C. The reaction mixture was stirred at room temperature for 1 h. Water and CH2Cl2 were added. The layers were separated and the aqueous was extracted with CH2Cl2. The combined organics were dried (MgSO4), filtered and concentrated in vacuo, to yield 2-chloro-1-[(3R)-3-fluoropyrrolidin-1-yl]ethanone (4.7 g).
