To a solution of the 2-methylindole (65 mg) in THF (1 mL) stirred under argon cooled on dry ice/acetone was added n-butyl lithium (2 M in pentane, 0.8 mL). After 2 minutes, potassium tert-butoxide (1M in THF, 1 mL) was added and the mixture was allowed to warm to approximately −20° C. After 5 minutes, a precipitate was noted and the mixture was cooled to −70° C. 1-Cyclohexyl-4-(5-fluoro-2-methoxyphenyl)-4-methylpentan-2-one (Example 15) (100 mg) in THF (1 mL) was added dropwise and the mixture was stirred for 20 minutes at −70° C. The reaction was quenched with EtOH (0.5 mL). The mixture was diluted with EtOAc, washed with water, dried, filtered, and evaporated. Chromatography over silica gel (methylene chloride-hexanes (1:2)) gave the title compound as an oil (0.095 g).
