Hydrochloric Acid → 2-(2-Hydroxypropan-2-yl)phenol

Participants

Reaction Steps

A solution of 10.0 ml (11.31 g, 83.1 mmol) of 2′-hydroxyacetophenone and 50 ml of tetrahydrofuran was placed in an ice bath and treated with 120.0 ml (168.0 mmol) of 1.4M methyllithium in tetrahydrofuran, which was added dropwise over 30 minutes. The reaction mixture first became cloudy and then cleared up. After stirring for 18 hours, the solution was acidified with 4% aqueous hydrochloric acid. The layers were separated. The organic phase was washed with 30 ml of brine, dried over sodium sulfate, and concentrated. A total of 12.05 g of 2-(dimethylhydroxymethyl)phenol was isolated.
