Procedure:
5-Chloro-3-methyl-2-pyridin-3-yl-1H-indole (Example 2, 1.350 g, 4.659 mmol) is suspended in THF (40 mL) and cooled to 0° C. KHMDS (0.5M in toluene, 32.6 mL, 16.3 mmol) is added dropwise. After 1 h, 4-bromomethyl-2,6-dimethyl-benzoic acid ethyl ester (4.95 g, 18.2 mmol) in THF (10 mL) is added dropwise. The mixture is allowed to warm to room temperature overnight. The mixture is then quenched with saturated aqueous ammonium chloride and diluted with dichloromethane. The aqueous phase is extracted with ethyl acetate, dried over MgSO4, filtered and concentrated in vacuo. Purification of the residue by silica gel chromatography (dichloromethane-methanol, 1:0 to 99:1 to 49:1 to 97:3) affords 2,6-dimethyl-4-(5-chloro-3-methyl-2-pyridin-3-yl-indol-1-ylmethyl)-benzoic acid ethyl ester as an orange solid.
