Reaction Steps

A solution was prepared using 2-[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]-N-hydroxyethanimidamide (Example 275A) (0.100 g, 0.308 mmol), 2-(methylthio)benzoic acid (0.076 g, 0.463 mmol), HATU (0.176 g, 0.463 mmol), triethylamine (1.0 mL, 13.6 mmol) and anhydrous DMF (10 mL). 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 0.042 g (30% yield) of pure product: MS (ES) m/z 456 (M+).
