実験手順

At room temperature, a solution of sodium hydroxide (19 mg) in methanol (0.25 ml) and water (0.05 ml) was added to a solution of 1-[4-(4-acetyl-1,3-thiazol-2-yl)piperidin-1-yl]-2-[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]ethanone (190 mg) and 2,6-difluorobenzaldehyde (67 mg) in methanol (0.12 ml). The reaction mixture was stirred at room temperature overnight. After aqueous work-up, the mixture was extracted with ethyl acetate and the extracts were dried with sodium sulphate and concentrated under reduced pressure. The residue was purified chromatographically. This gave (2E)-3-(2,6-difluorophenyl)-1-[2-(1-{[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazol-4-yl]prop-2-en-1-one (160 mg).
