4-[4-(Ethoxycarbonyl)-1,3-thiazol-2-yl]piperidinium chloride (VI-1, 8.23 g) is reacted analogously to Example IV-1 with 2-(3,5-dimethyl-1H-pyrazol-1-yl)-2-methylpropanoic acid (5.42 g). This gives, after chromatographic purification, ethyl 2-{1-[2-(3,5-dimethyl-1H-pyrazol-1-yl)-2-methylpropanoyl]piperidin-4-yl}-1,3-thiazole-4-carboxylate (9.64 g, 80%)
