실험 절차

Dissolve 6-fluoro-4-iodo-N-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)pyridin-3-amine (0.20 g, 0.55 mmol) in ethanol (5.5 mL). Add pyridinium p-toluenesulfonate (0.014 g, 0.055 mmol). Heat the reaction mixture at 50° C. overnight. Remove the solvent under reduced pressure. Purify by FCC (0.1% to 1% 2 M NH3 methanol solution/CH2Cl2) to give the title compound (44 mg, 28%) with 100% HPLC purity. MS (ES) m/z 283 [M+1]+.
