実験手順: To a solution of 17.4 g (0.15 mol) of dry TMEDA in 600 mL of hexanes, 60.0 mL (0.15 mol) of 2.5 M nBuLi in hexanes was added at room temperature. This mixture was stirred for 30 min, and then 27.6 g (0.15 mol) of 2-phenylanisol was added. This mixture was stirred for 4 hr at 55° C., then heated to 100° C., and a solution of 28.0 g (0.38 mol) of DMF in 200 mL of THF was added dropwise with vigorous stirring. The resulting mixture was evaporated to dryness, and the product was isolated by flash chromatography on silica gel 60 (40-63 um, eluent: hexanes-diethyl ether from 100:1 to 20:1, vol.) to yield 26.1 g (82%) of the title product. This mixture was stirred for 4 hr at 55° C. The resulting mixture was evaporated to dryness the product was isolated by flash chromatography on silica gel 60 (40-63 um, eluent: hexanes-diethyl ether from 100:1 to 20:1, vol.)

実験手順: To a suspension of 2-phenylphenol (20.00 g, 0.117 mol) and K2CO3 (32.48 g, 0.235 mol) in 235 mL of anhydrous acetone was added a neat solution of dimethylsulfate (15.56 g, 0.123 mol) dropwise through a syringe over 5 minute at RT under argon. The resulting thick suspension was stirred over night at RT and 100 mL of EtOH was added. After 1 hour, the mixture was diluted with ether and water. The aqueous layer was extracted with EtOAc. The combined organic layers were washed with water, brine and dried with MgSO4. After filtration, the solvents were removed and dried under high vacuum to give afford 2-phenylanisole (18.85 g, 87% yield). 1H NMR (300 MHz, CDCl3): δ 3.80 (s, 3H), 6.95–7.60 (m, 2H), 7.28–7.35 (m, 3H), 7.37–7.43 (m, 2H), 7.50–7.55 (m, 2H).
