2-(2-Methoxy-6-methylphenyl)-2-propanol → 2-Iso-propyl-3-methylanisole

Participants

Reaction Steps

A solution of 2-(2-methoxy-6-methylphenyl)-2-propanol (0.50 g, 2.77 mmol) in ethyl acetate-acetic acid (9:1, 10.0 mL) at room temperature was stirred under a H2 atmosphere for 16 h. The mixture was filtered through a Celite plug and the solvent was removed under reduced pressure. The residue was dissolved in hexanes and washed with water. The organic layer was dried MgSO4, filtered and concentrated under reduced pressure to afford 2-iso-propyl-3-methylanisole (0.45 g, 100%) as colorless oil, which was used for the next step without further purification: 1H NMR (300 MHz, DMSO-d6): δ 7.01 (dd, J=12.0 Hz, 11.7 Hz, 1 H), 6.78 (d, J=12.0 Hz, 1 H), 6.70 (d, J=11.7 Hz, 1 H), 3.74 (s, 3 H), 3.28 (m, 1 H), 2.26 (s, 3 H), 1.24 (d, J=10.8 Hz, 6 H); TLC conditions: Uniplate silica gel, 250 microns; Mobile phase=ethyl acetate-hexanes (1:9); Rf=0.80.
