Procedure:
Preparation of 2-((1E)buta-1,3-dienyl)-1-methoxybenzene (compound 100A) Methyltriphenylphosphonium bromide (42.9 g, 0.12 mol) was suspended in 400 ml of anhydrous THF under nitrogen and cooled to −78° C. Sodium hydride (60% in mineral oil, 6.0 g, 0.15 mol) was added portionwise. The reaction mixture was allowed to warm up slowly to room temperature and stirred at the same temperature for 1 h, then 2-methoxycinnamaldehyde (16.2 g, 0.10 mol) in 200 ml of THF was added dropwise at room temperature, and stirred at the same temperature for 3 h. Water (200 ml) and diethyl ether (800 ml) were added. The organic layer was separated, dried over sodium sulfate, concentrated, and purified using normal phase chromatography to afford the title product. 400 MHz 1H NMR (CDCl3) δ 7.48-6.56 (m, 7H), 5.32 (d, 1H), 5.16 (d, 11H), 3.84 (s, 3H). Step 2. Preparation of 2-butyl-1-methoxybenzene (compound 100B) A mixture of the product from example 100A (12.8 g, 0.08 mol) and palladium/carbon (10%, 50% water, 12 g) in 400 ml of ethyl acetate was hydrogenated at 50 psi, at room temperature overnight, then filtered through Celite®, and concentrated to give 100B. 400 MHz 1H NMR (CDCl3) δ 7.16 (m, 2H), 6.85 (m, 2H), 3.81 (s, 3H), 2.61 (m, 2H), 1.57 (m, 2H), 1.38 (m, 2H), 0.92 (t, 3H). Step 3. Preparation of 2-butylphenol (compound 100C) To a stirred solution of the product from example 100B (13.1 g, 0.08 mol) in 400 ml of dichloromethane at −78° C. was added dropwise a solution of boron tribromide (100.2 g, 0.4 mol) in 200 ml of dichloromethane. After the completion of addition of boron tribromide, the reaction mixture was maintained at −78° C. for 1 h, then allowed to reach room temperature and stirred at the same temperature overnight. The mixture was cooled to 0° C., and carefully quenched with 100 ml of water. The mixture was extracted with ethyl acetate, washed with brine, dried over sodium sulfate, and concentrated to give 100C. 400 MHz 1H NMR (CDCl3) δ 7.10 (m, 2H), 6.86 (m, 1H), 6.78 (d, 1H), 4.61 (brs, 1H), 2.61 (m, 2H), 1.60 (m, 2H), 1.40 (m, 2H), 0.96 (t, 3H).
