Benzyl Alcohol → 3-(3-Benzyl-4-hydroxy-phenyl)-2-ethoxy-propionic acid benzyl ester

Participants

Reaction Steps

Oxalyl chloride (0.364 g, 2.87 mmol) was added dropwise to a mixture of 3-(3-benzyl-4-hydroxy-phenyl)-2-ethoxy-propionic acid (0.345 g, 1.15 mmol) and a catalytic amount of DMF in dry DCM (2.0 mL). The mixture was stirred for 17 h at room temperature before the excess oxalyl chloride was evaporated in vacuo. The remaining carboxylic acid chloride was redissolved in dry DCM (3.0 mL) and benzyl alcohol (0.15 g, 1.38 mmol) was added under nitrogen atmosphere. After stirring for 24 h at room temperature the solvent was removed in vacuo and the resulting oil was purified by column chromatography using DCM/MeOH (96:4) as the eluent to afford the title compound as an oil (0.22 g, 36.8%). Mass Spectrum: M−H+ 388.94.
