Yield: 100%
Reaction Conditions:
with aluminum (III) chloride in toluene at 130; for 2 h;Inert atmosphere;
Steps:
1.4. General method for demethylation of 3b, 3d-l and 3n-p with aluminum trichloride (4b, 4d-l and 4n-p).[10]
General procedure: AlCl3 (2.5 equiv.) was slowly added to a solution of 3b, 3d-l and 3n-p (1.0 equiv.) in toluene (0.15 M) under a N2 atmosphere. The mixture was refluxed at 130 °C for 2 h and by TLC (Pet. ether/EtOAc 4/1) full conversion was shown. The cooled mixture was poured into an 3 M HCl (aq.) solution, the organics were extracted with ethyl acetate (3 times), washed with brine, dried over MgSO4 and concentrated to give the desired 4-(benzoyl)phenols (4b, 4d-l and 4n-p) as solids.
