α-(Aminomethylene)-9-(methoxymethyl)-9H-purine-6-acetamide and the ethyl acetate, 3 and 8, have been synthesized by catalytic hydrogenation of 6-cyanomethylene-9-methoxymethylpurine derivatives 2 and 7 which were obtained by the substitution of 6-chloro-9-(methoxymethyl)purine (1) with α-cyanoacetamide and ethyl cyanoacetate, respectively. Substitution of 3 and 8 with amines gave the corresponding
α-(氨基亚甲基)-9-(甲氧基甲基)-9 ħ嘌呤-6-乙酰胺,乙酸乙酯,3和8,已通过催化氢化合成6-氰基亚甲基-9- methoxymethylpurine衍生物的2和7得到该用α-氰基乙酰胺和氰基乙酸乙酯分别取代6-氯-9-(甲氧基甲基)嘌呤(1)。用胺取代3和8,得到相应的N-取代的α-(氨基亚甲基)-9-(甲氧基甲基)-9 H-嘌呤-6-乙酰胺和乙酸乙酯4和10。反应3用哌啶,得到9-(甲氧基甲基)-9 ħ嘌呤-6-乙酰胺(5)。
