Procedure

A 0.15 quantity of the compound obtained in Example 327 and 0.18 ml of 1,8-diazabicyclo[5,4,0]undec-7-ene were dissolved in 3 ml of ethanol, 0.15 g of (bromomethyl)cyclopropane was then added to the obtained solution, and the obtained mixture was heated and refluxed overnight. After cooling, water was added to the obtained reaction mixture, and ethyl acetate extraction was performed. The organic layer was washed twice with water and concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1). The obtained crystals were recrystallized from aqueous 80% ethanol, thereby yielding 42 mg of white powdery 3-[2-(3-cyclopropylmethoxy-4-difluoromethoxyphenyl)oxazol-4-yl]-1-(3-methylpyridin-2-yl)propan-1-one.
