150 °C

A mixture of 6.1 g of 6-methyl-3-pyridinol, 5.5 g of 1-isopropyl-3-azetidinol, 0.3 g of potassium hydroxide and 25 ml of benzyl alcohol is stirred for 16 hours under nitrogen in a bath at 150° C. After cooling, the reaction mixture is diluted with 50 ml of ether and extracted with 30 ml of 4 N hydrochloric acid. The aqueous phase is separated off, rendered alkaline with concentrated sodium hydroxide solution and extracted with 100 ml of methylene chloride. 3-(3'-Isopropylamino-2'-hydroxy-propoxy)-6-methyl-pyridine is isolated from the crude product thus obtained by bulb tube distillation at 130°-140° C. bath temperature and 0.04 mm Hg. It is identical in its properties with the product obtained in Example 19.
