3-[4-(Ethoxycarbonyl)-1,3-thiazol-2-yl]piperidinium chloride (VI-2, 5.32 g) is reacted analogously to Example IV-1 with [5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetic acid (4.00 g). This gives, after chromatographic purification, ethyl 2-(1-{[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-3-yl)-1,3-thiazole-4-carboxylate (5.7 g, 69%).
