tert-Butyl 4-{4-[(E)-2-(naphthalen-1-yl)ethenyl]-1,3-thiazol-2-yl}piperidine-1-carboxylate (IV-2, 171 mg) is deprotected analogously to Example II-2 and then reacted analogously to Example I-81 with [5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetic acid (100 mg). After chromatographic purification, this gives 2-[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]-1-(4-{4-[(E)-2-(naphthalen-1-yl)ethenyl]-1,3-thiazol-2-yl}piperidin-1-yl)ethanone (180 mg).
