Allgemeine Beschreibung
Contains varying amounts of anhydride
Synthese
A pentane solution of tert-butyllithium (1.28 M, 51.5 mL, 66.0 mmol) was added dropwise to a solution of 4-isopropoxybromobenzene (5.61 g) in THF (150 ) at -78 C under an argon atmosphere. mL) to a solution of 4-isopropoxybromobenzene (5.61 g) in THF (150 ). The mixture was stirred for 1 hour. Trimethyl borate (5.02 mL, 45.0 mmol) was was added to the mixture as a pure liquid. Stir the mixture at -78 C for 1 hour. Allow the reaction mixture to warm to room temperature. Stir the reaction mixture for another 1 hour. Quench the mixture with saturated NH4Cl Quench the mixture with saturated NH4Cl aqueous solution. Evaporate the mixture under reduced pressure. Adjust the pH of the residue to 3 by adding 3 M aqueous HCl. Extract the mixture with dichloromethane. Wash the extract with brine. Dry the extract with Na2SO4. Na2SO4 to dry the extract. Evaporate the extract under reduced pressure. The residual solid was washed with hexane. Filter the solid to obtain 4-isopropoxyphenylboronic acid.
