Product 1

HCID 227574744-[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

Procedure

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.
