Reaktionsschritte

A mixture of 4-(4-chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole (1.91 g), ethyl 2-(2-hydroxyphenyl)acetate (1.00 g), anhydrous potassium carbonate (0.76 g) and N,N-dimethylformamide (20 mL) was stirred at 90° C. for 2 hrs. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated. The obtained residue was subjected to silica gel column chromatography to give ethyl 2-[2-[4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyloxy]phenyl]acetate as an oil (1.35 g, 54%) from a fraction eluted with ethyl acetate-hexane (1:4, v/v).
