反応手順

To a solution of 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-[4-(4-{5-[2-(hydroxymethyl)phenyl]-4,5-dihydro-1,2-oxazol-3-yl}-1,3-thiazol-2-yl)piperidin-1-yl]ethanone (0.55 g) in dichloromethane (10 ml) were added, at room temperature, thionyl chloride (0.24 g) and one drop of DMF, and the mixture was then refluxed for 2 hours. Subsequently, the reaction mixture was concentrated under reduced pressure. This gave, without further purification, 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-[4-(4-{5-[2-(chloromethyl)phenyl]-4,5-dihydro-1,2-oxazol-3-yl}-1,3-thiazol-2-yl)piperidin-1-yl]ethanone (0.59 g).
