2-Bromo-4-hydroxybenzaldehyde Use and Manufacturing
With an inert atmosphere of nitrogen to a mixture of A-11 (16 g, 74.40 mmol) in dichloromethane (150 mL) was added BBrThe mixture of aqueous OH (30percent, 160 m1) and 3-bromophenol (10.04 g, 58 mmol) was heated to 70-75 °C and then ethanol (5 ml) was added in one portion followed by dropwise addition of chloroform (28 ml, 0.35 mol) for lh at 75 °C. The reaction mixture was stirred for additional 3h at that temperature. After cooling to room temperature and acidification with 10N HC1, most of the by-products were removed by steam distillation. The residue was cooled and the precipitate was separated by filtration. Column chromatography of the crude solid on silica gel with a mixture of hexane/ethyl acetate (2: 1 , v/v) as eluent afforded 1.75 g (15percent) of 2-bromo- 4-hydroxybenzaldehydeIntermediate 9[2-bromo-4-[tert-butyl(dimethyl)silylloxy-phenyllmethanolTo a solution of Step A:
