Reaction Steps
4-[4-(Ethoxycarbonyl)-1,3-thiazol-2-yl]piperidinium chloride (VI-1, 5.50 g) is reacted analogously to Example IV-1 with [3-(trifluoromethyl)-1H-pyrazol-1-yl]acetic acid (3.86 g). This gives, after chromatographic purification, ethyl 2-(1-{[3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate (5.1 g, 62%).
