実験手順

To a mixture of 2-(2-methyl-1-imidazolyl)-4-(4-trifluoromethylphenyl)-5-oxazolepropanol (700 mg), 2-methylphenol (432 mg), tributylphosphine (607 mg) and tetrahydrofuran (10 mL) was added 1,1′-(azodicarbonyl)dipiperidine (750 mg) at room temperature and the mixture was stirred for 1 h. The reaction mixture was concentrated and the residue was subjected to silica gel column chromatography. The title compound was obtained as crystals from an eluate from ethyl acetate-hexane (2:3, v/v). Recrystallization from acetone-isopropyl ether gave colorless prism crystals (591 mg, 67%). melting point: 101-102° C.
