A series of twenty two compounds containing thiazolo[3,2-a]
pyrimidine carboxamide nucleus was synthesized by using
microwave. Substituted acetoacetanilide was condensed with
thiourea and substituted benzaldehydes in the presence of
p-toluenesulfonic acid as catalyst in ethanol to get 2-thioxo-
1,2,3,4-tetrahydropyrimidine carboxamide. In the second step,
1,2,3,4-tetrahydropyrimidine carboxamides were treated with
chloroacetic acid, anhydrous sodium acetate and glacial acetic
acid to yield the title compounds. The reaction progress and
purity of the synthesized compounds were monitored by TLC
using silica gel G and by determining their melting points.
Structures of title compounds were confirmed by elemental analysis, IR, 1H NMR and mass spectral data. The
antipsychotic activity for title compounds was performed using
albino mice by rotarod and tail suspension method.
Compounds have shown antipsychotic activity comparable
with the standard risperidone. The 2D, 3D QSAR and
molecular docking studies were performed using VLife MDS
3.5 software. The molecular modelling studies reveals that
more potent antipsychotics from this series can be generated
by substituting electronegative group at para and meta position
of N-phenyl ring and less bulky group at 5-phenyl ring of
thiazolo[3,2-a]pyrimidine-6-carboxamide nucleus.
