Reaction Steps

To a solution of 2-[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]-N-hydroxyethanimidamide (Example 275A) (0.05 g, 0.154 mmol) in anhydrous acetonitrile (10.0 mL) under N2, was added 2-chloro-5-iodobenzoyl chloride (0.159 g, 0.528 mmol) and triethylamine (0.5 mL, 6.81 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 0.019 g (22% yield) of pure product: MS (ES) m/z 570 (M+1).
