Toluene → 4-(3-Chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole

Participants

Reaction Steps

Thionyl chloride (4.45 ml) was added dropwise to a mixture of 3-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzylalcohol (15.0 g) and toluene (200 ml) at 0° C. After stirring at room temperature for 1 hour, water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The remaining crystals were recrystallized from ethyl acetate-hexane to obtain 4-(3-chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole (13.4 g, yield 84%) as pale-yellow crystals. m.p. 79-80° C.
