Procedure

Methyl 3-hydroxy-4-methoxybenzoate (500 mg, 2.75 mmol) and triphenylphosphine (1.08 g, 4.12 mmol) were dissolved in THF (13 ml), the solution was cooled in an ice bath and 2-(3-bromophenyl)-ethanol (662 mg, 3.29 mmol) and DIAD (886 mg, 4.12 mmol) were added sequentially. Stirring was continued for 3 h at room temperature. The reaction mixture was evaporated to dryness and the residue purified by preparative RP HPLC (water/ACN gradient) to give 900 mg of the title compound.
