Procedure

2,2-Dimethoxypropane (1.94 ml, 15.8 mmol) and PPTS (0.079 mg, 0.32 mmol) are added to a solution of (S)-3-(4-Iodo-phenoxy)-propane-1,2-diol (0.93 g, 3.16 mmol) in DMF (20 ml), and the resulting solution is left to stir at room temperature overnight. The solvent is removed in vacuo and the residue is purified by chromatography (SiO2, EtOAc:Iso-hexane) to afford (R)-4-(4-Iodo-phenoxymethyl)-2,2-dimethyl-[1,3]dioxolane as a colourless oil.
