To a mixture of 4-(4-chlorophenyl)-2-(2-methyl-1-imidazolyl)-5-oxazolepropanol (635 mg), 4-methylphenol (432 mg), tributylphosphine (607 mg) and tetrahydrofuran (5 ml) was added 1,1′-(azodicarbonyl)dipiperidine (757 mg) at room temperature, and the resulting mixture was stirred for 1 hour. After the reaction mixture was concentrated, the residue was subjected to silica gel column chromatography, and 4-(4-chlorophenyl)-2-(2-methyl-1-imidazolyl)-5-[3-(4-methylphenoxy)propyl]oxazole was obtained as an oil (475 mg, 58%) from an ethyl acetate-hexane (1:1, v/v)-eluted fraction.
