Yield:135-19-3 99%

Reaction Conditions:

with copper oxide (I);2-(N,N-dimethylamino)ethanol;lithium hydroxide monohydrate;potassium hydroxide in dimethyl sulfoxide at 100; for 24 h;Inert atmosphere;Reagent/catalyst;Temperature;

Steps:

General Procedure B.

To a test tube containing a magnetic bar was added aryl halide (1.0 mmol), Cu2O (14.3 mg, 0.1 mmol), KOH (169 mg, 3.0 mmol), 2-dimethylaminoethanol (0.3 mL, 3.0 mmol), and DMSO/H2O (1.5 mL/0.5 mL). After flushing with argon, the mixture was stirred in a preheated oil bath at 100 °C for 24 h. After cooled to ambient temperature, the reaction mixture was distributed in aqueous HCl (5 %) and ethyl acetate. The organic layer was washed with water and brine, dried over anhydrous MgSO4, and concentrated under vacuum. The crude product was further purified by column chromatography (EtOAc/n-Hexane) to provide the phenols.
