Aromatic alkanols are provided by reacting an aromatic compound with a 1,2-alkylene oxide in the presence of a synthetic porous crystalline material possessing a Constraint Index of not greater than about 3. Thus, for example, isobutylbenzene is reacted with propylene oxide in the presence of zeolite Beta, ZSM-12 or MCM-22 to provide 2-(4-isobutylphenyl)propanol which can thereafter be oxidized to the corresponding carboxylic acid, the widely utilized anti-inflammatory agent ibuprofen (i.e., 2-(4-isobutylphenyl)-propionic acid).
