Synthesis of 1-Isopropylamino-3-(pyrazolo[1,5-a]pyridyloxy)-2-propanols
摘要:
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.

The present invention provides a fused heterocyclic compound having a tyrosine kinase inhibitory action, which is represented by the formula:
wherein
R1 is a hydrogen atom, a halogen atom, or an optionally substituted group bonded via a carbon atom, a nitrogen atom or an oxygen atom;
R2 is a hydrogen atom, or an optionally substituted group bonded via a carbon atom or a sulfur atom, or
R1 and R2, or R2 and R3 are optionally bonded to each other to form an optionally substituted ring structure;
R3 is a hydrogen atom or an optionally substituted aliphatic hydrocarbon group, or
R3 is optionally bonded to the carbon atom on ring A to form an optionally substituted ring structure;
ring A is an optionally substituted benzene ring; and ring B is
(i) an optionally substituted fused ring, or
(ii) a pyridine ring having optionally substituted carbamoyl (the pyridine ring is optionally further substituted).
