4,4,5,5-Tetramethyl-2-(2-methyl-5-nitrophenyl)-1,3,2-dioxaborolane Chemical Properties,Usage,Production
Synthesis
In a dry reaction flask, a mixture of aniline (3 mmol) and 14% HBr (6 ml) is cooled to 0 C. A solution of NaNO2 (3 mmol, 1.1 equiv.) in water (2.4 ml) is slowly added to the above reaction mixture, taking care not to raise the temperature above 0 C during the addition. The resulting mixture was stirred at 0 C for 30 minutes. It is then rapidly added by pipette to a stirred solution of B 2 pin2 (6 mmol, 2 eq.) and NaOAc (6 mmol, 2 eq.) in methanol (6 mL) at room temperature. The resulting mixture was stirred at room temperature for 1 hour. At the end of the reaction, the reaction mixture was concentrated directly under reduced pressure to remove methanol, water (30 mL) was added to the resulting residue and the aqueous layer was extracted with dichloromethane (3 30 mL). All organic layers were combined and the organic extract was dried with Na2SO4 and evaporated to obtain the crude product. The resulting residue was purified by silica gel column chromatography to obtain 2-methyl-5-nitrophenylboronic acid pinacol ester.
