Procedure

To a solution of 0.19 g (0.81 mmol) (6′-chloro-2-methyl-[3,4′]bipyridinyl-3′-yl)-methyl-amine in 8 ml THF were added 0.52 ml (0.83 mmol) of a 1.6 M solution of n-butyllithium in hexanes at −78° C. After 15 min 0.28 g (0.88 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-2-methyl-propionyl chloride were added. The reaction mixture was allowed to warm to room temperature during 30 min. After addition of a 0.2 M aqueous sodium hydroxide solution the mixture was extracted with three portions of dichloromethane. The combined organic layers were dried over sodium sulfate and concentrated. Flash chromatography gave 0.30 g (73%) of the title compound.
