Procedure
A mixture of 4-(4-chlorophenyl)-2-oxazoleproprionic acid (0.5 g), benzyl bromide (0.25 ml), potassium carbonate (0.33 g) and dimethylformamide (DMF) (10 ml) was stirred for 3 hours at room temperature. The reaction mixture was poured into water to obtain crystals of benzyl 4-(4-chlorophenyl)-2-oxazolepropionate (0.664 g, 98%). Recrystallization from ether-hexane gave colorless prism crystals of mp 66°-67° C.
