Source of material
The title compound was synthesized with a total yield of 56% following the literature method with small modification [5]. Colorless crystals suitable for X-ray diffraction study were obtained from an acetone solution.
Experimental details
The hydrogen atoms were assigned with common isotropic displacement factors Uiso(H) = 1.2 times Ueq(C, aromatic ring, and methylene), Uiso(H) = 1.5 times Ueq(C, methyl), and Uiso(H) = 1.2 times Ueq(N, amino). The final refinement by using geometrical restraints, with C—H = 0.93 Å (aromatic ring), and C—H = 0.96 Å (methyl), C—H = 0.97 Å (methylene), N—H = 0.86 Å (amino).
Comment
Penciclovir and its oral form famciclovir are both potent and selective anti-herpesvirus agents [5]. The purity and the crystal type of the medicine is very important for pharmaceutical industrial synthesis. The title compound is a key intermediate for the syntheses of penciclovir and famciclovir. Before the syntheses of related pharmaceuticals, the purification of the raw materials is to guarantee the high purity of the products. However, we did not find the crystal profile of the title compound in literatures up to now.
As shown in the figure the molecular structure of the title compound is composed of two acetoxy groups, isopentane, and the purine fragment. All the bond lengths are in the normal ranges [6]. There are intermolecular N—H⋯N hydrogen bonds, by which adjacent molecules are connected into one-dimensional chain along [100].
