Reaction Steps

To a solution of 2-propyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile (Example 153A) (0.200 g, 0.793 mmol) in anhydrous acetonitrile (30 mL) was added Cs2CO3 (0.298 g, 0.915 mmol) and 2-(bromomethyl)-5-cyclopropyl-1,3,4-thiadiazole (0.300 g, 1.37 mmol). The mixture was heated under N2, for 2 h. Upon cooling, the mixture was partitioned between EtOAc and water. The organic phase was separated, dried (MgSO4) and concentrated in vacuo. The residue was purified by flash chromatography (0-20% EtOAc-hexanes gradient) to afford a pure product (0.189 g, 61% yield): MS (ES) m/z 390 (M+).
