A mixture of 2-chloro-4-(4-chlorophenyl)-5-[3-(2-methoxyphenoxy)propyl]oxazole (500 mg), 2-propylimidazole (1.10 g), potassium carbonate (1.38 g) and N,N-dimethylformamide (10 ml) was stirred at 120-130° C. for 4 hours. The reaction mixture was poured into water (100 ml), the resulting solid precipitate was filtered, air-dried and recrystallized from acetone-hexane to give 4-(4-chlorophenyl)-5-[3-(2-methoxyphenoxy)propyl]-2-(2-propyl-1-imidazolyl)oxazole as pale yellow prisms (233 mg, 39%). Melting point 89-90° C.
