실험 절차
N-Bromosuccinimide (380 mg, 2.137 mmol) was added portionwise to a solution of cis-2,6-dimethyl-4-[3-(2-methyl-3-furanyl)phenyl]morpholine (580 mg, 2.137 mmol) in chloroform (10 mL) at 0° C. The reaction was stirred at 0° C. for 1 hour. Crude LC/MS showed desired product can be seen and no starting material left, so the reaction mixture was diluted with ethyl acetate and washed with water, brine, water and brine. The organic layer was dried (sodium sulfate), filtered and concentrated under reduced pressure.
