EXAMPLE 1 2-Methoxy-5-(3-(((4-phenylpiperidin-4-yl)methoxy)methyl)-5-(trifluoromethyl)phenyl)pyrimidine. tert-Butyl 4-((3-bromo-5-(trifluoromethyl)benzyloxy)methyl)-4-phenylpiperidine-1-carboxylate (60. 0 mg, 0.11 mmol), 2-methoxy-5-pyridine boronic acid (72.0 mg, 0.47 mmol), and tetrakis(triphenylphosphine) palladium(0) (17.1 mg, 0.011 mmol) were combined in dry tetrahydrofuran (2 mL) in a microwave tube and sealed. The mixture was flushed with nitrogen then 0.35 mL of a 1 N potassium hydroxide aqueous solution was introduced. The mixture was heated at 120° C. for 1 h via microwave. After cooling to room temperature, the reaction mixture was concentrated and treated with a trifluoroacetic acid/methylene chloride mixture (1:1, 2 mL) for 1 h. The solvent was removed in vacuo and the resulting crude mixture passed through a strong cation exchange column. After washing the column with several volumes of methanol, the product was eluted by washing the column with 2 M ammonia in methanol. Concentration and preparative HPLC afforded 21.0 mg (42percent) of the desired compound as its TFA salt. 1H-NMR (CDCl3, 500 MHz) delta 8.57 (s, 2H), 7.54 (s, 1H), 7.25-7.31 (m, 8H), 4.40 (s, 2H), 4.03 (s, 3H), 3.40 (s, 2H), 2.83-2.88 (m, 2H), 2.64-2.69 (m, 2H), 2.10-2.18 (m, 2H), 1.77-1.86 (m, 2H).
