실험 절차

To a solution of 2-[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]-N-hydroxyethanimidamide (Example 275A) (0.100 g, 0.308 mmol) in anhydrous acetonitrile (10.0 mL) under N2, was added 2,5-dichloro-3-pyridinecarbonyl chloride (0.223 g, 1.10 mmol) and triethylamine (1.0 mL, 13.6 mmol). The mixture was then heated in a microwave at 150° C. for 30 min. Upon cooling, the mixture was poured onto a biotage prepak column and the mixture was purified by flash chromatography (0-25% EtOAc-hexanes gradient) to give 0.021 g (14% yield) of pure product: MS (ES) m/z 480 (M+1).
