Procedure
To a mixture of AlCl3 (45 g, 0.337 mol) in 1,2-dichloroethane (DCE, 250 ml) at 0° C. was added 1-adamantyl carbonyl chloride (36.6 g, 0.228 mol) in DCE (150 ml). 3-fluorophenol (21 g, 0.183 mol) in DCE (100 ml) was added slowly at 0° C. The reaction was followed by TLC (heptane/toluene 50/50). The mixture was poured onto HCl 2N, extracted with AcOEt, washed with Nat-HCO3 and brine, dried over Na2SO4, filtered and concentrated under vacuum. Purification by flash chromatography (heptane/toluene 8/2) gave 27 g of 1-adamantyl (2-fluoro-4-hydroxyphenyl)methanone (48% as solid).
