Reaction Steps
A mixture of 3-[2-chloro-4-(4-chlorophenyl)-5-oxazolyl]-N-[4-(diethylphosphonomethyl)phenyl]propionamide (0.40 g), imidazole (0.20 g), potassium carbonate (0.41 g) and N,N-dimethylformamide (5 ml) was stirred at 120° C. for 2 hrs. The reaction mixture was poured into water, and the precipitated crystals were collected by filtration through a glass filter. The obtained crystals were washed with water and dried by ventilation. Recrystallization from acetone-isopropyl ether gave 3-[4-(4-chlorophenyl)-2-(1-imidazolyl)-5-oxazolyl]-N-[4-(diethylphosphonomethyl)phenyl]propionamide as pale-yellow prism crystals (0.33 g, 78%). melting point: 196–197° C.
