4-BROMO-2-ISOPROPOXY-1-METHOXYBENZENE

反应条件: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 5-bromo-2-methoxyphenol (0.200 g, 1 mmol) in DMF (4 mL) was added potassium carbonate (0.209 g, 1.5 mmol) and isopropyliodide (120 μL, 1.2 mmol), the reaction mixture was stirred at room temperature (20° C.) for 3 h. After this time the crude reaction mixture was diluted with ethyl acetate (100 mL) and washed with water (2×100 mL). The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo to afford a yellow oil (200 mg, 0.81 mmol, 82%). No further purification was required. After this time the crude reaction mixture washed with water (2×100 mL) The organic layer was dried over magnesium sulfate filtered concentrated in vacuo

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Reaction and post treatment were carried out in the same manner as in Reference Example 7-(a) except for using 10.1 g (49.8 mmol) of 5-bromo-2-methoxyphenol, and using 15 ml of isopropyl iodide in place of 1-bromo-2-chloroethane, whereby 10.4 g of the title compound was obtained as a pale yellowish solid.
