実験手順

A mixture of (2R,3R)-3-(2,4-difluorophenyl)-3-hydroxy-2-methyl-4-(1H-1,2,4-triazol-1-yl)thiobutyramide (19.7 mg) and 2-bromo-1-[4-(1,2,3-thiadiazol-4-yl)phenyl]ethanone (27.4 mg) in acetonitrile (3.0 ml) was stirred at room temperature for 1.0 hour. The solution was diluted with ethyl acetate (10 ml), washed with saturated sodium hydrogen carbonate solution (5 ml) and brine (5 ml), dried over anhydrous sodium sulfate, then concentrated in vacuo. The mixture was purified by silica gel column chromatography developed by hexane-ethyl acetate (1:1) to give (2R,3R)-2-(2,4-difluorophenyl)-3-{4-[4-(1,2,3-thiadiazol-4-yl)phenyl]thiazol-2-yl}-1-(1H-1,2,4-triazol-1-yl)butan-2-ol as a pale yellow solid (14.1mg). EI-MS: m/z 497 (M+); 1H-NMR (CDCl3): δ 1.26(3H, d, J=6.9 Hz), 4.10(1H, q, J=6.9 Hz), 4.31(1H, d, J=14.3 Hz), 4.92(1H, d, J=14.3 Hz), 6.04(1H, s), 6.76˜6.87 (2H, m), 7.48˜7.58(1H, m), 7.58(1H, s), 7.68(1H, s), 7.92(1H, s), 8.06(2H, d, J=8.4Hz), 8.16(2H, d, J=8.4 Hz), 8.73(1H, s).
