Synthesized as described in Example 23 using 2-methyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile, 2-bromopropionitrile (2 eq) and Cs2CO3 (2 eq) with heating at 90° C. for 30 min. After aqueous workup, purification by flash chromatography afforded 1-(1-cyanoethyl)-2-methyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile (0.033 g, 27% yield) (MS (ES) m/z 278 (M+1)) and 1-(2-cyanoethyl)-2-methyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile (0.043 g, 35% yield) (MS (ES) m/z 278 (M+1).
