The title compound, C~11~H~13~N~3~O, is a key intermediate in the synthesis of cardiotonic agents. The asymmetric unit consists of two molecules of the same enantiomer and the crystal packing is stabilized by intermolecular N—H...O hydrogen bonds.
In the title compound, C 17 H 17 N 3 OS 2 , the fused thiophene and pyrimidine rings are almost coplanar. The amino group is involved in both intramolecular and intermolecular hydrogen bonds, the latter linking the molecules into a centrosymmetric dimer.
In the title molecule, C 31 H 28 N 2 O 2 , the piperidinone ring adopts the usual twist-boat conformation. The aryl rings at positions 2 and 3 are axial and those at positions 5 and 6 are equatorial. In the crystal structure, there are no hydrogen bonds nor are there any significant Á Á Á stacking i
