Procedure

4-Methyl-2-[4-(trifluoromethyl)phenyl]-1,3-thiazole-5-carboxylic acid (50 mg, 0.174 mmol) and methyl 2-{[4-(2-aminoethyl)phenoxy]methyl}benzoate hydrochloride (59 mg, 0.183 mmol) were mixed in DMF (4 ml) and the mixture was then cooled in an ice-bath. TBTU (59 mg, 0.183 mmol) was added and followed by DIPEA (47.2 mg, 0.366 mmol). The mixture was stirred at room temperature overnight. Ethyl acetate and sodium hydrogencarbonate aqueous solution (sat.) were added. The two phases were separated. The organic phase was washed with water and dried (magnesium sulphate) and evaporated. Chromatography of the residue on a column (ISOLUTE® SI, 2 g/6 ml) using DCM and then MeOH/DCM (0.5:99.5) as eluant gave 59 mg the desired product, white solid, yield 61%.
