Procedure

To a solution of 33 mg (0.144 mmol) 2-chloro-3-(trifluoromethyl)benzoic acid (commercial), 75 mg (0.197 mmol) HATU and 90 ul (0.524 mmol) N-ethyldiisopropylamine in DMF (1 ml) was added a solution of 25 mg (0.131 mmol) rac-1-methyl-3-phenyl-piperidin-3-ylamine (Example A.1) in DMF (0.25 ml). The mixture was stirred at room temperature for 22 hours. The solvent was removed in vacuo. The residue was dissolved in ethyl acetate. The solution was washed once with water and twice with a saturated sodium carbonate solution. The aqueous layer was extracted once with ethyl acetate. The combined extracts were dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified on silica gel (Eluent: Heptane/ethyl acetate 0 to 100%) to provide 27 mg (52%) of the title compound as a light yellow oil. MS (m/e): MS (m/e): 397.2 (M+H)
