Vorschrift

To a solution of (E)-3-[5-(5-methyl-2-phenyl-4-oxazolylmethoxy)-2-benzofuranyl]-2-propen-1-ol (2.00 g) in tetrahydrofuran (100 ml), palladium-carbon (5%, 0.30 g) was added, followed by catalytic reduction at room temperature and under an atmospheric pressure of 1 atm. After the catalyst was filtered off, the filtrate was concentrated to yield 3-[5-(5-methylphenyl-4-oxazolylmethoxy)-2-benzofuranyl]propanol (yield 93%), which was then recrystallized from acetone-isopropyl ether to yield colorless prisms having a melting point of 101° to 102° C.
