Versuchsvorschrift

In the same manner as in Reference Example 4, methyl 5-hydroxybenzofuran-2-carboxylate was reacted with 4-chloromethyl-5-methyl-2-phenyloxazole to yield methyl 5-(5-methyl-2-phenyl-4-oxazolylmethoxy)bezofuran-2-carboxylate (yield 87%), which was then recrystallized from acetone-ethyl acetate to yield colorless prisms having a melting point of 177° to 178° C.
