실험 절차
The compound of Example 52A (400 mg, 2.05 mmol) was dissolved in DMF (2 mL) and N-chlorosuccinimide (328 mg, 2.46 mmol) was added. The mixture was heated to 80° C. overnight, concentrated and purified by column chromatography to give the chloro pyridine (234 mg, 50%). MS (DCI) m/z 230, 232 (M+H+).
