Procedure

Triethylamine (0.026 ml) was added to a stirred solution of (pyridin-2-yl)acetic acid hydrochloride (0.033 g, 0.19 mmol) in DMF (2.5 ml) at 0° C. 1-Hydroxy-benzotriazole containing 8% of water (0.034 g) and then 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.044 g) was added and the mixture was stirred for 50 min. Piperazine-1-carboxylic acid 4-(5-trifluoromethyl-pyridin-2-yloxy)-phenyl ester hydrochloride (0.070 g) in a mixture of DMF (1 ml) and triethylamine (0.032 ml) was added and stirring was continued over night at room temperature. The solvent was removed in vacuum and the residue was partitioned between dichloromethane (10 ml) and water (10 ml). The organic phase was washed with water (10 ml), dried over sodium sulfate, filtered and evaporated. The residue was triturated with ether-petroleumsether 1:1 and the (2+1 ml). The residue was dried to give the title compound. White solid, m.p. 143-146° C.; HPLC-MS m/z: IR (KBr) □ 1732 (C═O), 1643 (C═O).
