Synthese
3-Bromo-2-naphthol is synthesised using 2-bromo-3-methoxynaphthalene as a raw material by chemical reaction. The specific synthesis steps are as follows:
General procedure: To a Schlenk flask were added 2-bromo-3-methoxynaphthalene(1.0 equiv), aryl boronic acid (2.2 equiv), K
2CO
3 (3.0 equiv), Pd(PPh3)4 (2.5 mol%), and degassed EtOH/toluene/water (1/1/1) under Ar atmosphere. The mixture was heated at 90 °C until thecompletion of the reaction. Then the mixture was cooled to room temperature, and DCM was added. The mixture was washed with NaOH solution (20% wt), and the aqueous phase was extracted with DCM (2 × 20 mL). The combined organic phase was washed with brine (20 mL) and dried overanhydrous MgSO
4. After removing the solvent, the residue was dissolved in anhydrous DCM. Thesolution was cooled to -78 °C, and BBr3 (1 M in DCM, 5.0 equiv) was added slowly by syringe. Thenthe mixture was warmed up to room temperature and stirred until the complete consumption of thestarting material. The mixture was poured into the ice water (50 mL) and extracted with DCM (3 × 50mL). The combined organic phase was washed with brine (100 mL) and dried over anhydrous Na
2SO4. After removing the solvent, the residue was purified by silica gel chromatography to give 3-Bromo-2-naphthol.
