2-(4-溴-2-甲基苯基)丙-2-醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To 4-bromo-2-methyl-benzoic acid methyl ester (3.7 g, 15.9 mmol) in diethyl ether (10 mL) at 0° C. under N2 was added 3N methylmagnesium bromide in diethyl ether (21 mL, 63 mmol). The mixture was stirred 16 h at room temperature. The mixture was poured into 1N hydrochloric acid (aq, 10 mL) and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride, dried (MgSO4), filtered, and concentrated in vacuo to a crude colorless oil. Flash chromatography (SiO2, 5% ethyl acetate/hexane) gave the title compound as a colorless oil (2.6 g, 72%). 1H NMR (300 MHz, CDCl3): δ ppm 1.63 (s, 6 H) 2.56 (s, 3 H) 7.26–7.34 (m, 3 H). extracted with ethyl acetate The organic layer was washed with saturated sodium chloride dried (MgSO4) filtered concentrated in vacuo to a crude colorless oil
