実験手順

A mixture of 4-[4-(methylsulfonyl)phenyl]-5-(tetrahydro-2H-pyran-4-yl)pent-1-en-3-one (0.50 g), 5-(1-hydroxyethyl)-1,3-thiazole-2-carbaldehyde (0.28 g), 3-benzyl-5-(2-hydroxyethyl)-4-methyl-1,3-thiazol-3-ium chloride (43 mg), triethylamine (0.09 mL), tetrahydrofuran (6 mL) and ethanol (6 mL) was stirred with heating under reflux for 2 hr. The reaction mixture was concentrated, the residue was subjected to basic silica gel column chromatography, and eluted with ethyl acetate, and the fraction was concentrated. The residue was subjected to silica gel column chromatography, and the title compound (0.57 g, yield 75%) was obtained as a colorless oil from a fraction eluted with ethyl acetate. MS: 480 (MH+).
