Participants

Reaction Steps

To a mixture of 4-(4-chlorophenyl)-2-(2-methyl-1-imidazolyl)-5-oxazolebutanol (1.32 g), 2-methylphenol (865 mg), tributylphosphine (1.21 g) and tetrahydrofuran (30 ml) was added 1,1′-(azodicarbonyl)dipiperidine (1.51 g) 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-[4-(2-methylphenoxy)butyl]oxazole was obtained as crystals (1.61 g, 96%) from an ethyl acetate-hexane (1:1, v/v)-eluted fraction. Recrystallization from acetone-isopropyl ether gave colorless prisms. Melting point 71-72° C.
