该中间体在本合成路线中的序号：(II)2,6-Dichloropurine (I) is condensed with cyclobutylamine (II) in the presence of diisopropylethylamine in hot butanol to produce the 6-cyclobutylamino purine (III). The 2-chloro group of purine (III) is then displaced with 4-amino-N-methylacetanilide (IV) in N-methylpyrrolidone at 145 C to furnish the target diamino purine derivative.
