Procedure
A solution of 2,4-dimethyl-3-hydroxymethylfuran (11 g.) in dichlormethane (25 ml.) was added to a cooled slurry of triphenylphosphine hydrobromide (34 g.) in dichloromethane to give a clear solution. After standing a further 30 minutes at room temperature the bulk of the solvent was distilled off and the residue was crystallized from a 1:4 parts by volume mixture of methanol and ethylacetate to yield a buff colored solid (27.2 g.) of (2,4-dimethyl-3-furyl)methyl triphenylphosphonium bromide, m.p. 248°-249°.
