Participants

Reaction Steps

To a mixture of 3-{4-[(4-hydroxymethyl-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}benzonitrile (10.0 g) and toluene (200 mL) was added thionyl chloride (3.74 g), and the mixture was heated under reflux for 1 hr. The reaction mixture was concentrated and ethyl acetate was added to the residue. The organic layer was washed successively with saturated aqueous sodium hydrogen carbonate and saturated brine, dried over anhydrous magnesium sulfate and concentrated to give 3-{4-[(4-chloromethyl-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}benzonitrile (10.3 g, yield 98%) as colorless crystals. Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 150-151° C.
