Synthesis and characterization of derived imines from 4-imino-5,6,7,8-tetrahydro-1-benzothieno[2,3-d]pyrimidin-3(4H)-amine
The synthesis and characterization of derived imines from 4-imino-5,6,7,8-tetrahydro-1-benzo thieno[2,3-d]pyrimidin-3(4H)-amine 3 has been developed in 3 steps through the reaction of heteroaromatic o-aminonitrile 1 with triethyl orthoformate afforded the corresponding imido ester 2 followed by cyclization with hydrazine hydrate to furnish iminothienopyrimidineamine 3 and finally the imination ...

In the title compound, C(12)H(16)N(4)S, the fused benzothio-phene and the pyrimidine rings are coplanar [dihedral angle = 1.61 (6)°]. Three C atoms of the cyclohexene ring (at positions 3, 6 and 7) are disordered over two sites with an occupancy ratio of 0.702 (8):0.298 (8). The cyclo-hexene ring in both the major and minor components adopts a half-chair conformation. The crystal structure is s...
