Reaction Steps

To a solution of (1Z)-2-[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]-N-hydroxyethanimidamide (0.050 g, 0.154 mmol) in anhydrous acetonitrile (2.0 mL) under N2, was added 2,5-difluorobenzoyl chloride (0.121 g, 0.177 mmol) and N,N-diisopropylethylamine (0.50 mL, 5.21 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 0.029 g (42% yield) of pure product: MS (ES) m/z 446 (M+).
