2-(1-Adamant­yl)-1-{4-[(2-chloro-9-isopropyl-9H-purin-6-yl)amino­meth­yl]phen­yl}ethanone

The structure of the title compound, C(27)H(32)ClN(5)O, consists of two crystallographically independent conformers differing slightly in all geometric parameters. Both contain nearly planar purine and benzene ring systems [maximum deviations of 0.046 (3) and 0.005 (2) Å, respectively], the dihedral angles between them being 76.44 (6) and 82.39 (6)°, and an adamantane cage consisting of three fused cyclo­hexane rings in almost ideal chair conformations, with C—C—C angles in the range 108.7 (2)–110.6 (2)°. The carbonyl plane and the benzene ring are almost coplanar [dihedral angles of 6.43 (9) and 0.64 (8)° in the two conformers]. The crystal structure is stabilized by inter­molecular N—H⋯N inter­actions that link adjacent mol­ecules into dimers and by some non-bonding contacts of the C—H⋯Cl type.
