L-Proline (5.8 mg, 0.050 mmol) was added to a solution of 3-quinolin-6-ylbutanal (50 mg, 0.25 mmol) in chloroform (0.5 mL) at 0° C. followed by addition of N-chlorosuccinimide (36.9 mg, 0.276 mmol). The mixture was stirred at RT for 2 h, diluted with hexanes and filtered. The filtrate was concentrated and purified by chromatography on silica gel with EtOAc in methylene chloride (0-10%) to afford the desired product (0.048 g, 82%). LCMS: (M+H)=234.1/236.1.
