L-Proline (10 mg, 0.1 mmol) was added to a solution of [1-(4-methoxyphenyl)cyclopropyl]acetaldehyde (100 mg, 0.53 mmol) in chloroform (1 mL) at 0° C. followed by addition of N-chlorosuccinimide (84 mg, 0.63 mmol). The reaction mixture was stirred at ambient temperature for 2 h. The mixture was diluted with hexanes and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by flash chromatography eluting with ethyl acetate in hexanes (0-10%) to afford the desired product.
