Procedure

To a solution of 2-ethylphenol (6.9 g, 56.5 mmol), triphenylphosphine (15.7 g, 60 mmol) and ethanol (6 mL, excess) in tetrahydrofuran (100 mL) was added dropwise DIAD (12.1 g, 60 mmol). After stirring for 18 hours, mixture was evaporated and the residue was chromatographed on silica gel (heptane/ethyl acetate 9/1) to give 1-ethoxy-2-ethyl benzene (7.2 g) as a clear liquid. GC-MS shows one peak, RT=5.6 minutes. MS 150 (M+).
