79% With sodium hydroxide; dimethyl sulfate In water Synthesis of 3,4,5-trimethoxybromobenzene 18
A mixture of 74 g (0.32 mol) of 4-bromo-2,6-dimethoxy-phenol 17 and 32 g (0.8 mol) of NaOH in 850 ml of H2O was cooled to 10° C. and 45 ml (0.48 mmol) of dimethyl sulfate was added.
The mixture was refluxed for 3 h and an equal amount of dimethyl sulfate (total 0.96 mol) was then added.
The mixture was refluxed for another 3 h.
Upon cooling overnight, the gray product solidified and was filtered off and dissolved in 1.2 l of ether.
The ether solution was filtered to remove insoluble impurity and washed sequentially with 5percent NaOH solution (200 ml), water (2*200 mL), and brine (200 mL).
The ether phase was dried over Na2SO4 to give a off-white solid, which was recrystallized in hexane (300 ml) to give 62.3 g (79percent) of 18.

YieldReaction ConditionsOperation in experiment
100% With boron tribromide In dichloromethane at -78℃; for 1 h; 7.44 g (30.24 mmol) of 3,4,5-trimethoxy-1-bromobenzene and 70 mL of dry dichloromethane were placed in a four-necked flask and cooled to -78 ° C. Next, 325.0 g (99.8 mmol) of BBr was gradually added dropwise, and then the mixture was stirred for 1 hour. Further, after raising the temperature to room temperature, it was added to 200 mL of ice water to precipitate a precipitate. Next, the precipitate was filtered to obtain 6.8 g (yield quant.) Of 3,4,5-hydroxy-1-bromobenzene as a white powder. 3,4,5-Hydroxy-1-bromobenzene had an m/z of 206.01 ([M+H]+)

The black reaction mixture was allowed warm to room temperature and stir overnight. The reaction mixture was poured into ice water (1000 mL), and extracted with EtOAc (2×1000 mL) The EtOAc layers were dried over anhydrous Na2SO4, and concentrated to give 5-bromobenzene-1,2,3-triol (XXV) as a pale solid. (40 g, 0.195 mol, 96.4percent yield)1H NMR (DMSO-d6, 400 MHz): δ ppm 6.40 (s, 1H), 9.28 (brs, 3H); ESIMS found C6H5BrO3 m/z 205.0 (M+H).
54% With boron tribromide In dichloromethane at -75 - 25℃; To a CH2CI2 solution (40 mL) of 5-bromo-l,2,3-trimethoxybenzene (4.94 g, 20 mmol) was slowly added, at -75°C under nitrogen, a CH2CI2 solution of ΒΒ (1 M, 60 mL), and the mixture was allowed to warm to 25 °C. After overnight stirring, the reaction mixture was poured into ice/water (200 mL) and extracted with ethyl acetate. The combined organic extract was washed with water, dried over anhydrous Na2S04, and filtered off from an insoluble fraction.
