(5-Bromo-2-methoxyphenyl)methanol (1.89 g, 8.71 mmol) was dissolved in 25 mL of dichloromethane. Imidazole (0.711 g, 10.45 mmol) was added, followed by addition of tert-butyldimethylsilyl chloride (1.378 g, 9.14 mmol). After stirring at room temperature for 15 minutes, the reaction was complete by thin layer chromatography. CH3OH (1 mL) was added and the reaction mixture was stirred for 5 minutes and was washed with 1 M aqueous HCl (3*15 mL) and brine (15 mL), and was dried over sodium sulfate. After filtration, the filtrate was concentrated to provide the title compound, which was used without additional purification. 1H NMR (400 MHz, Chloroform-d) delta ppm 7.60 (dd, J=2.5, 1.2 Hz, 1H), 7.33 (dd, J=8.7, 2.6 Hz, 1H), 6.71 (d, J=8.6 Hz, 1H), 4.74 (d, J=1.0 Hz, 2H), 3.82 (d, J=1.1 Hz, 3H), 0.99 (s, 9H), 0.15 (s, 6H); MS(ESI+) m/z=329.8 (M+H)+.

Application of 80866-82-6, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 80866-82-6, name is 5-Bromo-2-methoxybenzyl alcohol. This compound has unique chemical properties. The synthetic route is as follows.

Reference Example 26 Imidazole (3.45 g) and t-butyldimethylchlorosilane (17.6 g) were added to a solution of 5-bromo-2-methoxybenzyl alcohol (10.0 g) in DMF (100 ml) under cooling with ice and the mixture was stirred for two hours. The reaction mixture was added to ice-cooled water and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated. The residue was purified by silica gel column chromatography (n-hexane-ethyl acetate) to obtain [(5-bromo-2-methoxybenzyl)oxy](t-butyl)dimethylsilane (15.2 g).

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 80866-82-6, 5-Bromo-2-methoxybenzyl alcohol.

The mixture was stirred until complete solution was attained, then cooled to O0C, and diisopropylazodicarboxylate (0.136 mL, 0.7 mmol) was added dropwise. The reaction mixture was agitated at room temperature overnight, diluted with THF (2 mL) then treated directly with the Amberlyst resin (3 g, 4 mmol). This reaction mixture was agitated overnight and the resin was then filtered and washed with DMF (2 x 3 mL) and several portions of methanol. The product was eluted by treating the resin with a 20% solution of formic acid in methanol (5 mL) and washing with methanol (3 mL). The combined eluant and final wash was evaporated to provide the title compound (154 mg, 99%). LCMS (ESMS): m/z 447/9 (M+H+).
