실험 절차

2,6-Dimethyl-4-[4-(2-methyl-3-furanyl)-2-pyrimidinyl]morpholine (737 mg, 2.70 mmol) was dissolved in chloroform (13 mL), cooled in an ice bath and treated with N-bromosuccinimide (480 mg, 2.70 mmol). The resulting mixture was stirred at 0° C. for 1 hour. The reaction mixture was diluted with water and extracted with ethyl acetate (×2). The ethyl acetate layers were combined, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by SP4 Biotage column chromatography eluting with a gradient of 0-20% ethyl acetate in iso-hexane. Product containing fractions were combined and evaporated under reduced pressure to give the title compound (719 mg, 2.041 mmol, 76% yield) as a white solid. LC/MS [M+H]+=352/354.
