Procedure

To a stirred and refluxing mixture of 56 parts of lithium aluminum hydride in 1000 parts of tetrahydrofuran was added dropwise a solution of 359 parts of 2-(2,5-dimethylphenoxy)propanoic acid in 1000 parts of tetrahydrofuran. Upon completion, stirring was continued at reflux temperature for 1.50 hours. The reaction mixture was cooled and decomposed by the successive additions of 55 parts of water, 45 parts of a 15% sodium hydroxide solution and 190 parts of water and the whole was stirred for 30 minutes. The inorganic material was filtered off after acidification with hydrochloric acid solution. The filtrate was dried, filtered and evaporated. The residue was distilled, yielding 73 parts of 2-(2,5-dimethylphenoxy)-1-propanol; bp. 150° C. at 11 mm. pressure (131).
