Source of materials
The title compound is easily available by a known synthetic protocol [5]. In a typical precepitation reaction 0.3 g of the title compound were dissolved in 5 mL methanol. Evaporation at room temperature yielded colourless crystals.
Experimental details
All hydrogen atoms were identified in difference Fourier syntheses. The hydrogen atoms were placed on calculated positions with the help of the SHELX program (AFIX 43, 23 or 137 option) [1] with Uiso(H) = k times Ueq(N,C), where k = 1.5 for CH3 H atoms and 1.2 for other H atoms.
Comment
The title compound is a very important intermediate in the production of Omarigliptin. Omarigliptin (MK-3102) is an oral hypoglycemic agent of super long-lasting dipeptidyl peptidase-4 (DPP-4) developed by Merck & Co., USA. Its mechanism of action is through inhibiting the degrading of the in vivo dipeptidyl peptidase-4 (DPP-4) on the GLP-1, prolonging the action time of glucagon-like peptide-1 (GLP-1), thereby increasing the blood concentration of the endogenous GLP-1 and GIP, and ultimately improving blood glucose control [6].
The molecular structure of the title compound is shown in the figure. The bond lengths and angles are within normal ranges [7]. The crystal structure analysis of the title compound revealed that the two rings A (C1—C2—C3—N1—N2) and B (C2—C3—C4—N3—C5) are almost planar. The dihedral angle between ring A and ring B is 1.7(2)°. In the crystal of the title compound, there are intermolecular N—H⋯O hydrogen bonds connecting adjacent molecules to chains. According to the N⋯O distance of 2.791(2) Å, this hydrogen bond is to be classified as medium strong.
