Versuchsvorschrift

A mixture of 4-(4-chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole (1.73 g), 3-(4-mercaptophenyl)propionic acid (1.00 g), triethylamine (1.22 g) and N,N-dimethylformamide (20 mL) was stirred at room temperature for 2 hrs. The reaction mixture was poured into water, acidified with 2N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate and concentrated to give crystals of 3-[4-[[4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyl]sulfanyl]phenyl]propionic acid. Recrystallization from ethyl acetate gave colorless prism crystals (1.85 g, 73%). melting point: 157-158° C.
