Reaction Steps

The 4-[4-(3-morpholin-4-yl-propoxy)-phenyl]-3-oxo-butyronitrile is then converted to the appropriate aminopyrazole by the following method: Under Ar(g), 0.095 gms. of the 4-[4-(3-morpholin-4-yl-propoxy)-phenyl]-3-oxo-butyronitrile is dissolved in 2 mL of anhydrous EtOH and then is treated with 0.100 gms. anhydrous hydrazine. The reaction mixture is then heated overnight at 65° C., subsequently, cooled to room temperature and concentrated in vacuo providing 5-[4-(3-morpholin-4-yl-propoxy)-benzyl]-2H-pyrazol-3-ylamine which is use in crude form in the reaction of Example 58.
