2-(2-methylpropyl)phenol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-Hydroxy-isobutyrophenone was prepared from phenol following the procedure described in Canadian Journal of Chemistry, 31, 1956, 851. To a solution of 2-hydroxy-isobutyrophenone (2g, 12.2 mmol) in trifluroacetic acid (14 g, 122 mmol) was slowly added triethylsilane (26.8 mmol). The solution was stirred at room temperature for 6 hours. Saturated sodium bicarbonate solution was added to the reaction mixture, followed by ether. The layers were separated, and the aqueous layer was extracted with ether. The organic layers were combined, dried over magnesium sulfate, and concentrated. The crude material was distilled under vacuum (about 9.3×10−4 MPa, 75° C.). The distillate was washed with potassium hydroxide solution, followed by addition of hydrogen chloride solution, and extraction with ether. The ether layers were combined, dried over magnesium sulfate, and concentrated to give 1.0 g (55%) of 2-isobutylphenol. 1H NMR (300 Mhz, δ, CDCl3): 7.0 (m, 2H), 6.8 (t, 1H), 6.7 (d, 1H), 4.6 (br. s, 1H), 2.4 (d, 2H), 1.9 (s, 1H), 0.9 (d, 6H). The layers were separated the aqueous layer was extracted with ether dried over magnesium sulfate concentrated The crude material was distilled under vacuum (about 9.3×10−4 MPa, 75° C.) The distillate was washed with potassium hydroxide solution followed by addition of hydrogen chloride solution, and extraction with ether dried over magnesium sulfate concentrated
