反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Acetic anhydride (1.25 mL, 12.2 mmol) was added to a solution of 5-amino-2-methyl phenol (1.0 g, 8.1 mmol) in acetic acid (6 mL), and the reaction was refluxed for 5 mins. Then the reaction mixture was cooled to room temperature and the product was solidified. It was filtered off and washed with water (4 mL) and dried to obtain the product along with the trace amount of O-acylated product. The mixture, to which was added 3-bromophenetole (1.33 g, 6.6 mmol) and Cs2CO3 (2.927 g, 9.0 mmol) in DMF (10 mL), was stirred overnight at 50° C. The reaction mixture was then diluted with water (10 mL) and extracted with ethyl acetate (3×20 mL). The combined extracts were dried over sodium sulfate and recrystallized from toluene to obtain the pure product 18a in 65% (yield over two steps) as an off-white solid. the reaction was refluxed for 5 mins It was filtered off washed with water (4 mL) dried to obtain the product along with the trace amount of O-acylated product extracted with ethyl acetate (3×20 mL) The combined extracts were dried over sodium sulfate recrystallized from toluene

実験手順: In DMF (96 ml) was dissolved 3-bromophenol (12 g). To the mixture was added potassium carbonate (12.5 g) and then 2-bromoethylethylether (6.7 ml), and the mixture was stirred at room temperature for 16 hours. The reaction mixture was added to water, and the mixture was extracted with ethyl acetate, washed with saturated brine and dried with magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column chromatography (hexane/ethyl acetate=12/1) to give 1-bromo-3-ethoxybenzene (11.6 g). the mixture was extracted with ethyl acetate washed with saturated brine dried with magnesium sulfate Under reduced pressure, the solvent was evaporated the residue was purified with silica gel column chromatography (hexane/ethyl acetate=12/1)
