To a solution of 3-methyl-4-chlorophenol (10.0 g, 69 mmol), triphenylphosphine (1.3 eq, 22 g), (S)-methyl lactate (1.3 eq, 9.4 mL) in DCM (230 mL) at 0° C. was added DEAD (1.2 eq, 13 mL) over 1 min. Reaction warmed to rt overnight. The mixture was then filtered through a pad of silica gel and concentrated. The residue was purified via flash chromatography eluting with 10% EtOAc/hexanes to provide the product as a colorless oil.
