Boron tribromide → 1-(4-Hydroxyphenyl)cyclohexane-1-carbonitrile

関与物質

反応手順

To a solution of 1-(4-methoxyphenyl)cyclohexanecarbonitrile (2 g, 9.29 mmol) in DCM (40 mL) at 0° C. under N2 was added dropwise BBr3 (2.63 mL, 27.87 mmol). The reaction was allowed to warm to room temperature and stirred for 48 hours. The mixture was stirred for 3 hours at 0° C. and quenched with water (30 mL). The mixture was separated and the organic layer was washed with a saturated aqueous solution of NaHCO3 then water. The combined organic extracts were dried over Na2SO4, filtered, concentrated in vacuo and purified by column chromatography on silica gel eluting with DCM:acetone (97:3) to give the title compound (1.71 g, 91%).
