PURPOSE:To obtain the title compound which is used as an intermediate of medicines readily in high yield, by allowing a specific compound to react with epichlorohydrin using a phase transfer catalyst, then adding a caustic alkali to complete the reaction. CONSTITUTION:The reaction of a compound of formula I (Ar is aryl) such as p-hydroxyphenylacetamide with epichlorohydrin of formula IV in the presence of a phase transfer catalyst of formula II (R' is 1-4C lower alkyl; R is benzyl, 1-8C lower alkyl; X is halogen, sulfate), when needed, in a solvent, preferably at 40-80 deg.C for 0.5-2hr to form a mixture of a compound of formula III and chlorohydrin of formula V. Then, a caustic alkali such as potassium hydroxide is added to the reaction mixture and heated at 70-80 deg.C for 1-3hr to complete the reaction whereby the subject compound of formula III is obtained, which is used as an intermediate of a drug having adrenergic blockade such as atenolol.
