Article abstract of DOI:10.3987/COM-96-7566

Treatment of the 4-hydroxypyrazolo[1,5-a]pyridine with glycidyl tosylate in the presence of base, followed by reaction with isopropylamine gave 1-isopropylamino-3-(pyrazolo[1,5-a]pyrid-4-yloxy)-2-propanol. In a similar manner, 1-isopropylamino-3-(pyrazolo[1,5-a]pyrid-6- and 1-isopropylamino-3-(pyrazolo[1,5-a]pyrid-3-yloxy)-2-propanol were also prepared.
