Reaction Steps

To a solution of 2,4,6-trimethylpyridine (0.14 g) in THF (1 mL) stirred under argon and cooled to −70° C., tert-butyl lithium (1.7M in pentane, 0.75 mL) was added dropwise over 2 minutes. After stirring for an additional 2 minutes, 4-(5-fluoro-2-methoxyphenyl)-4-methylpentan-2-one (Example 17) (0.22 g) in THF (0.8 mL) was added all at once. After 5 minutes, the reaction was quenched with EtOH (0.2 mL) and allowed to warm to room temperature. The mixture was diluted with EtOAc, washed with water, dried, filtered, and evaporated. Chromatography of the residue over silica gel (eluent: EtOAc-methylene chloride (2:98 to 8:92 gradient)) gave the product as an oil (0.19 g).
