反応手順

A mixture of 2-chloro-4-(4-chlorophenyl)-5-[3-(2-methylphenoxy)propyl]oxazole (1.00 g), 2-isopropylimidazole (661 mg), potassium carbonate (830 mg) and N,N-dimethylformamide (10 ml) was stirred at 120-130° C. for 1 hour. The reaction mixture was poured into water (100 ml) and extracted with ethyl acetate (10 ml×2). The organic layer was dried over anhydrous magnesium sulfate and then concentrated. The residue was subjected to silica gel column chromatography, and 4-(4-chlorophenyl)-2-(2-isopropyl-1-imidazolyl)-5-[3-(2-methylphenoxy)propyl]oxazole was obtained as an oil (333 mg, 28%) from an ethyl acetate-hexane (1:1, v/v)-eluted fraction.
