Related Products of 83647-43-2, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.83647-43-2, name is (3-Bromo-2-methylphenyl)methanol, molecular formula is C8H9BrO, molecular weight is 201.0605, as common compound, the synthetic route is as follows.
The compound I-1C (2 g, 10 mmol) obtained in the previous step was dissolved in dioxane (30 ml).Add 2N aqueous potassium carbonate solution (10 ml),Then, phenylboric acid (1.46 g, 12 mmol) and tetrakistriphenylphosphine palladium (150 mg, 0.12 mmol) were added, and the obtained reaction solution was replaced with nitrogen three times.The reaction was carried out at 100 C for 3 hours under a nitrogen atmosphere, and TLC showed the reaction was completed.After the methanol was rotated under reduced pressure, a saturated ammonium chloride solution (250 ml) was added.The mixture was extracted with ethyl acetate (150 mL¡Á3), and then evaporated. Ethyl acetate = 10/1 (volume ratio V / V)),Compound I-1D (1.36 g, pale yellow solid) was obtained.Yield: 68.9%.
Statistics shows that 83647-43-2 is playing an increasingly important role. we look forward to future research findings about (3-Bromo-2-methylphenyl)methanol.
