چکیده
The mol-ecular structure of the title compound, C(8)H(12)N(2)O, indicates that 2-isopropyl-6-methyl-pyrimidin-4-ol (the enol-form) undergoes an enol-to-keto tautomerism during the crystallization process. The pyrimidin-4(3H)-one group is essentially planar, with a maximum deviation of 0.081 (1) Å for the O atom. In the crystal structure, symmetry-related mol-ecules are linked into centrosymmetic dimers via pairs of inter-molecular N-H⋯O hydrogen bonds, generating R(2) (2)(8) rings. These dimers are stacked along the a axis.

The title compound, C(9)H(15)N(3)O, contains four mol-ecules (A, B, C and D) in the asymmetric unit. In the crystal, the A+A and D+D pairs form inversion dimers linked by pairs of N-H⋯O hydrogen bonds. The B+C pairing is linked by the same bonds. The dimers are further linked by weak C-H⋯O inter-actions.

Isopropyl (IPLA), N-methyl-N-isopropyl (MIPLA), N-ethyl-N-isopropyl (EIPLA), and N,N-diisopropyl (DIPLA) lysergamides were evaluated for lysergic acid diethylamide (LSD)-like activity. In rats trained to discriminate 0.08 mg/kg LSD tartrate from saline, each of the subject compounds completely substituted, with an ED50 two to three times larger than that of LSD except for DIPLA, which had an ED...

In the title compound, C(14)H(15)N(5)O(2), the whole mol-ecule apart from the terminal C atoms of the isopropyl group is located on a crystallographic mirror plane. An intra-molecular C-H⋯N hydrogen-bonding inter-action may stabilize the mol-ecular conformation. The crystal packing features weak slipped π-π inter-actions between the pyrimidine and the phenyl rings of symmetry-related mol-ecules...
