Procedure
A mixture of 6.00 g (34.2 mmoles) of 3-hydroxy-4-methyl-5-phenylisoxazole and 6.33 g (68.4 mmoles) of epichlorohydrin was stirred, whilst heating at 75° C., for 5 hours. At the end of this time, the excess epichlorohydrin was removed by distillation under reduced pressure, and the resulting residue was purified by column chromatography through silica gel, using a 2:1 by volume mixture of cyclohexane and ethyl acetate as eluent, to give 6.51 g (yield 71.1%) of the title compound as a colorless powder, melting at 82°-83° C.
