Participants

Reaction Steps

To a mixture of [4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]phenyl]methanol (1.0 g), methyl 2-(5-chloro-2-hydroxyphenyl)acetate (0.74 g), triphenylphosphine (1.08 g) and tetrahydrofuran (50 mL) was dropwise added a solution (40%, 1.79 g) of diethyl azodicarboxylate in toluene at room temperature, and the mixture was stirred for 15 hrs. The reaction mixture was concentrated and the residue was subjected to silica gel column chromatography to give methyl 2-[5-chloro-2-[4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyloxy]phenyl]acetate as an oil (0.68 g, 42%) from a fraction eluted with ethyl acetate-hexane (1:6, v/v).
