Reaction Steps
By substituting diethylaminoethyl chloride for the dimethylaminopropyl chloride and utilizing the 2,8,10-trimethyl-4H-pyrazolo[1,5-a]pyrazolo[4',3':5,6]pyrido-[3,4-e]pyrimidin-5(8H)-one product of Example 12 instead of 8-ethyl-2-methyl-4H-pyrazolo[1,5-a]pyrazolo[4',3':5,6]- pyrido[3,4-e]pyrimidin-5(8H)-one in the procedure of Example 4, 4-[2-(diethylamino)ethyl[-2,8,10-trimethyl-4H-pyrazolo[1,5-a]pyrazolo[4',3':5,6]pyrido[3,4-e]pyrimidin-5(8H)-one is obtained.
