実験手順

8.6 g of 5-chloro-8-ethyl-2-methyl-8H-pyrazolo[1,5-a]pyrazolo[4',3':5,6]pyrido[3,4-e]pyrimidine (0.03 mol) and 7.2 g of diethylamine are suspended in 50 ml of butyl alcohol and heated with stirring in an autoclave for 10 hours at 150°. After this time, the solvent is removed, the residue is treated with water and filtered off. Recrystallization from alcohol yields 8 g (83%) of N,N,8-triethyl-2-methyl-8H-pyrazolo[1,5-a]pyrazolo[4',3':5,6]pyrido[3,4-e]pyrimidin-5-amine; m.p. 106°-108°.
