To a solution of 4-((1,3-dioxolan-2-yl)methyl)benzoic acid (362 mg, 1.05 mmol) in DCM (9 mL) was added (1S)-2-(3,5-dichloro-1-oxido-pyridin-1-ium-4-yl)-1-(3,4-dimethoxyphenyl)ethanol (200 mg, 0.96 mmol) followed by DMAP (58 mg, 0.48 mmol) and EDC.HCl (396 mg, 1.9 mmol). The mixture was allowed to stir a room temperature for 18 hours and then water (20 mL) and DCM (20 mL) were added and the organic phase was passed through a hydrophobic frit. The solvent was removed in vacuo and the crude material was purified by silica gel column chromatography, eluting with 30-100% EtOAc in DCM, to afford the title compound as an off-white solid (497 mg, 97%).
