実験手順

A suspension of triphenylphosphine hydrobromide (11.9 g, 34.7 mmol) and methyl 3-hydroxy-4-hydroxymethylbenzoate (6 g, 35 mmol) in acetonitrile (65 ml, was heated at reflux for 1.5 h. The solvent was removed on a rotary evaporator under vacuum and the resulting solid was diluted in ethyl ether (30 ml). The product was isolated by filtration. Its properties were as follows:
