Benzyl Bromide → 3-(4-Benzyloxyphenyl)-2-hydroxypropionic acid ethyl ester

Participants

Reaction Conditions

Reaction Steps

Benzyl bromide (21.9 g) and potassium carbonate (35.3 g) were added to a solution of ethyl 3-(4-hydroxyphenyl)lactate (22.4 g) in dimethylformnamide (220 ml). The mixture was stirred at 50° C. for 2 hours. The reaction mixture was partitioned between ethyl acetate and water. The ethyl acetate layer was separated and dried over magnesium sulfate and then concentrated under reduced pressure. The residue was purified via chromatography silica gel column using hexane/ethyl acetate=7/3 as the eluant to give the desired compound (31.0 g) as a pale yellow oil.
