Reaction Steps

A mixture of 4-chloromethyl-2-(2-furyl)-5-methyl-1,3-oxazole (8.0 g), ethyl 3-chloro-4-hydroxybenzoate (7.38 g), potassium carbonate (5.09 g) and N,N-dimethylformamide (200 mL) was stirred at 90° C. for 2 hrs. Water was poured into the reaction mixture, and the precipitated crystals were collected by filtration and dried to give ethyl 3-chloro-4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}benzoate as brown crystals (9.90 g, yield 74%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 145-146° C.
