3,4-Dimethoxyphenylboronic acid Use and Manufacturing
General procedure: To a solution of arylamine (0.5 mmol, 1.0 equiv) in MeOH(1.0 mL) was added HCl (0.5 mL, 1.5 mmol, 3.0 equiv), followed by H2O (0.5 ml). This mixture was stirred 2 min, and the NaNO2 solution (0.25 mL) was then added. The NaNO2 solution was prepared by dissolving 35 mg ofNaNO2 in H2O (0.25 mL). This mixture was stirred 30 minat 0–5 °C, followed by HCl (135 mg, 1.5 mmol, 3.0 equivalents) in MeOH (1.0 mL). This mixture was stirred 60min. H2O (10 mL) was added to reaction mixture, then extracted with CH2Cl2 (50 mL, 3×). The combined organic layer was dried over Na2SO4, followed by evaporation to give the products.
