Versuchsvorschrift

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-bromo-5-chlorobenzoyl chloride (0.134 g, 0.529 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 0.029 g (36% yield) of pure product: MS (ES) m/z 523 (M+1).
