To a degassed solution of 0.130 g (0.35 mmol) of (4-bromo-2,6-dimethyl-phenyl)-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone (intermediate 1) and 0.147 g (0.70 mmol) of 3-trifluoromethoxy-phenyl boronic acid in 5 ml of DMF was added 2.50 ml of tribasic potassium phosphate solution (2M in water) drop by drop, followed by 0.022 g (0.019 mmol) of tetrakis-(triphenylphosphine)-palladium. This reaction mixture was stirred at 80° C. for two hours and subsequently cooled down to RT, then poured into crashed ice and extracted three times with CH2Cl2; the organic phases were washed with water, dried over magnesium sulfate, filtered and evaporated. The residue was purified by flash column chromatography (CH2Cl2/MeOH 1:0 to 95:5) to give 0.12 g (77%) of the title compound as light yellow amorphous solid. MS: 447.2 (MH+).
