92% | With aluminum (III) chloride In neat (no solvent) at 140 - 150℃; | p-Tolyl acetate 2b (10 gm, 0.067 mol) was in 500 mL round bottom flask containing aluminium chloride (10.7 gm, 0.08 mol). It was heated on an oil bath at 140-150 °C for 5-6 hr. The progress of the reaction was monitored by TLC using ethyl acetate:hexane as a solvent system. The reaction mixture was quenched with crushed ice and obtained solid product was extracted with ethyl acetate (2×50 mL). The organic extracts were washed with brine solution (2×15 mL) and dried over anhydrous sodium sulphate. The solvent was evaporated under reduced pressure to afford the corresponding crude compounds. The obtained compound 3b was recrystallized using aq. ethanol. Yield 92percent. M.p. 45-48 °C. |
80% | at 130℃; for 1 h; | To a solution of p-cresol (15 g, 139 mmol) in acetic anhydride (37.5 mL) was added pyridine (1.13 mL).After 12 h of stirring at 25 °C, the volatiles were evaporated. The resulting oil was taken up in diethylether, washed with 10percent aqueous sodium bicarbonate twice and brine once, and dried and evaporated togive the acetate (20.85 g, quant. yield) which was used without further purification; 1H NMR δ 7.15 (d, = 9 Hz, 2H, H-3 and 5), 6.95 (d, = 9 Hz, 2H, H-2 and 6), 2.32 (s, 3H, OMe), 2.25 (s, 3H, Me).To the crude ester (20.85 g, 0.14 mmol) was added anhydrous aluminium chloride (18.75 g, 0.14 mmol)and the mixture was heated for 1 h at 130 °C. It was then cooled to 25 °C, treated with ice (7.5 g),allowed to stand for 1 h, diluted with CH2Cl2, and stirred overnight. The organic phase phase wasseparated, dried, and evaporated to give the product (16.63 g, 80percent) as green crystals; mp 48–50 °C, (lit.,3550 °C); 1H NMR δ 12.10 (s, 1H, OH), 7.48 (d, = 1.8 Hz, 2H, H-6), 7.26 (dd, J = 8.4, 1.8 Hz, 1H, H-4),6.86 (d, J = 8.4 Hz, 1H, H-3), 2.32 (s, 3H, OMe), 2.25 (s, 2H,Me). |

36g of acetoxytoluene was added to a four-necked flask, heated to 110 ° C with anhydrous aluminum trichloride (36.77 g, 0.28 mol). After the addition, the temperature was raised to 165 ° C. After 1 hour of stirring at the same temperature, 1 19mL of 4mol / L hydrochloric acid solution was stirred at 80-90 ° C for 1 hour, then cooled to room temperature and stirred for 3 hours. Toluene (12.5mL * 6) extraction six times the solvent was evaporated and dried in vacuo to give the product 2-acetyl-p-cresol 35.85g |

89.2% | With N-Bromosuccinimide; dibenzoyl peroxide In tetrachloromethane at 50℃; for 3 h; | Acetic acid(4-methyl) phenolate 50.0gSoluble in 500ml of carbon tetrachloride, add 4.0g BPO,Stirring at 50 ° C,Add 71.5g NBS ((4-methyl) phenolate (II) acetate and NBS in 3 batches,The molar ratio of BPO was 1:1.2:0.05), and the reaction was kept for 3 hours. Filtering,The filtrate was concentrated under reduced pressure.The orange-red oil was added dropwise to petroleum ether and stirred to disperse, and a solid precipitated. After suction filtration, the filtrate was washed with water.After drying, it was concentrated under reduced pressure to give (4-bromomethylene) phenyl ester (III), 68.3 g.Yield 89.2percent, |
41% | With N-Bromosuccinimide; 2,2'-azobis(isobutyronitrile) In chloroform for 4 h; Inert atmosphere; Reflux | NBS (13.91 g, 0.12 mol, 0.9 eq) and AIBN (2.17 g, 0.01 mol,0.1 eq) were placed in a Schlenk flask and put under an argonatmosphere. CHCI3was added followed by p-to\y\ acetate (19.67 g, 0.13 mol). The mixture was refluxed for 4 h. After cooling down the volume of the mixture was reduced on rotavap to approximately a third and the suspension was filtered. 200 mL of CHCI3was added to the filtrate and it was 3x washed with 80 mL of water, the combined organic layers were dried with MgSC>4, filtered and volatiles were removed on rotavap. 5 mL of AcOEt was added, the mixture was shortly sonicated and while stirring, 40 mL of hexane was added causing precipitation. The mixture was put to a freezer overnight and then filtered washing the white solid with 25 mL of hexane giving 12.05 g (41 percent, 0.05 mol) of the product. It was stored in the freezer. The NMR spectrum was in accordance with the literature (J. Org. Chem. 1981, 46 (15), 3029-3035) |
