Acetyl chloride → 1-Propanol,3-[(5-methyl-1h-pyrazolo[4,3-b]pyridin-7-yl)amino]-,1-acetate

Participants

Reaction Steps

The title compound was prepared from 7(3-hydroxypropylamino)-5-methyl-1H-pyrazolo[4,3-b]pyridine (1.125 g) and acetyl chloride by the general method of Example 4 with the following addition. After removal of solvents under reduced pressure the crude reaction mixture was dissolved in water and brought to pH 9 with 10% sodium hydroxide. The resulting solid was collected and dried before purifying by column chromatography under the conditions used for Example 4. A clear gum was obtained which on trituration with ether gave the title compound as a white solid, m.p. 115°-119° C.
