In the title compound, C6H6ClN3O2, all non-H atoms are approximately coplanar [maximum deviation = 0.012 (4) Å]; an intra-molecular N-H⋯O hydrogen bond occurs between the amino group and the carbonyl group. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into supra-molecular chains propagated along .
The title compound, C40H47FN2O5, crystallizes with two independent but similar mol-ecules in the asymmetric unit. In the crystal, mol-ecules are linked into chains along  by inter-molecular N-H⋯O hydrogen bonds.
In the title compound, C28H29FN3O3PS, the pyrimidine ring is oriented at a dihedral angle of 50.9 (2)° with respect to the floro-benzene ring, while the two phenyl rings bonding to the same P atom are twisted with respect to each other, making a dihedral angle of 62.2 (2)°. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯F hydrogen bonds into a… (More)
In the title compound, C(16)H(20)O(5), the dihedral angle between the planar rings, viz. benzene and cyclo-propane, is 52.1 (2)°. Mol-ecules are connected in the crystal via weak inter-molecular C-H⋯O hydrogen bonds, forming chains in the  direction.
The title compound, C(8)H(8)BrNO(2), does not show any significant inter-molecular π-π or C-H⋯π inter-actions in the crystal packing except for one weak Br⋯Br [3.715 (1) Å] inter-action.
