실험 절차

A mixture of 2-chloro-4-(4-chlorophenyl)-5-[3-(2-methylphenoxy)propyl]oxazole (1.00 g), imidazole (680 mg), potassium carbonate (1.38 g) and N,N-dimethylformamide (5 ml) was stirred at 120-130° C. for 1 hour. The reaction mixture was poured into water (100 ml), and the solid precipitate was filtered, air-dried and recrystallized from acetone-isopropyl ether to give 4-(4-chlorophenyl)-2-(1-imidazolyl)-5-[3-(2-methylphenoxy)propyl]oxazole as pale yellow prisms (662 mg, 61%). Melting point 113-114° C.
