Procedure

To 3-ethylphenol (3.42 g, 28 mmol) in THF (20 mL) at ice bath was added triphenylphosphine (9.5 g, 36.4 mmol) and then (R)-methyl 2-hydroxypropanoate (2.94 mL, 31 mmol). And then DIAD (8.2 mL, 42 mmol) was added dropwise to the above cole solution. The mixture was stirred at room temperature for 16 hr. The solvent was removed and the residue was purified by silica gel to obtain the title compound.
