Versuchsvorschrift

22 g of crude 2-methoxy-3-(3'-methanesulphonyloxy-2'-hydroxy-propoxy)-pyridine, 50 ml of isopropylamine and 150 ml of isopropanol are heated for 16 hours under reflux. After working up analogously to Example 14, 3-(3'-isopropylamino-2'-hydroxypropoxy)-2-methoxy-pyridine is obtained, which melts at 50°-65° C. after recrystallisation from ether-pentane. After reaction with half the equivalent amount of fumaric acid, the neutral fumarate of melting point 146°-147° C. (recrystallised from acetone) is obtained.
