The mixture is filtered, the filtrate is concentrated, the residue is taken up in dichloromethane, the solution is extracted with dilute sodium hydroxide solution and then with water, and the organic phase is dried over MgSO4. Removal of the solvent by distillation under reduced pressure results in a solid residue which is washed with diisopropyl ether to give 9.7 g (59% yield) of 2-[2-(4-fluorophenyl)-4-thiazolylmethyloxy]acetophenone as yellowish crystals of melting point 104°-106° C.
