Procedure

To a solution of 2-[3-(3-chloro-2-hydroxypropoxy)phenyl]-4-trifluoromethylimidazole (3.8 g.) in methanol (150 ml.) is added powdered potassium hydroxide (3. g.) and the mixture is allowed to stir 4 hours at room temperature. Glacial acetic acid (2.75 ml.) is added and the mixture concentrated under reduced pressure 920 mm. Hg.) over steam. The resulting residue is stirred with water, filtered and recrystallized from xylene to yield 2.5 g. of 2-[3-(2,3-epoxypropoxy)phenyl]-4-trifluoromethylimidazole is obtained, m.p. 145°-146.5° C.
