合成路线2

该中间体在本合成路线中的序号:(V)

Condensation of 2,6-dichloropurine (I) with 3-chloroaniline (II) in hot pentanol yielded the 6-anilino purine (III). This was then alkylated at the N-9 with iodoethane and K2CO3 to afford (IV). Finally, displacement of the 2-chloro of (IV) with cis-1,2-cyclohexanediamine (V) at 150 C furnished the title compound.
