YieldReaction ConditionsOperation in experiment
62% With aluminum (III) chloride; In 1,2-dichloro-benzene; at 140℃; for 3h; To a solution of commercially available 2-bromophenol (10; 10.0 g,57.8 mmol) in anhydrous CH2Cl2 (50 mL) in a round-bottom flask were added AcCl (5.0 g, 63.6 mmol) and Et3N (4.67 mL, 63.6 mmol) and the mixture was stirred at r.t. for 1 h. The solvent was evaporated under reduced pressure to give the pure 2?-bromophenylacetate (9; 12.18 g, 56.6 mmol, 98percent). The ester 9 was dissolved in 1,2-dichlorobenzene (100 mL), then AlCl3 (11.3 g, 84.9 mmol) was added. The mixture was heated and stirred at 140 °C for 3 h. Ice and 10percent HCl were added till the solution was slightly acidic (pH). The organic phase was separated and the aqueous phase was extracted with CH2Cl2 (3 × 50 mL). The combined organic phases were dried (MgSO4) and filtered. The CH2Cl2 was evaporated under vacuum. The crude residue was treated with hexane (300 mL) and cooled at ?20 °C when most of the para-substituted by-product 11 crystallized and filtered off. The solution was filtered through silica gel and washed with hexanetill the 1,2-dichlorobenzene was eluted, then the eluent was changed to CH2Cl2?Et3N (20:1). After chromatography and evaporation of the eluent, the pure product 8 was isolated as a colorless oil; yield: 7.55 g (35.1 mmol, 62percent). IR (ATR): 3008, 2925, 2570, 1643, 1473, 1428, 1364, 1250, 1146, 1071, 968, 836, 775, 738, 627, 595, 523, 437 cm?1. 1H NMR (CDCl3): delta = 12.97 (s, 1 H, OH), 7.73 (m, 2 H, 4-H, 6-H), 6.82 (t,J = 7.9 Hz, 1 H, 5-H), 2.66 (s, 3 H, CH3). 13C NMR (CDCl3): delta = 204.3 (C=O), 158.9 (C-2), 139.6 (C-4), 129.9 (C-6), 120.5 (C-1), 119.6 (C-5), 112.0 (C-3), 26.7 (CH3). MS: m/z = 214 [M+], 216 [M+ + 2, 100percent], 201, 199, 143, 145, 92, 77, 63. Anal. Calcd for C8H7BrO2: C, 44.68; H, 3.28. Found: C, 44.50; H, 3.19.
