Source of material

The title compound is easily available by a known literature synthesis [5]. In a typical reaction 0.2 g of the title compound was dissolved in 6 mL methanol. Evaporation at room temperature yielded colourless crystals of tert-butyl 4-((4-(4-bromo-2-fluorophenylamino)-6-methoxyquinazolin-7-yloxy)methyl)piperidine-1-carboxylate.

Experimental details

The hydrogen atoms (except H3a) were placed on calculated positions with the program SHELXL (AFIX 43, 23, 13 or 137 option) [3].

Discussion

The title compound is a very important intermediate in the production process of Vandetanib. Vandetanib (trade name Caprelsa, Astra Zeneca) is an anti-cancer drug used for the treatment of certain tumours of the thyroid gland [6]. Its pharmacological property is that of a kinase inhibitor for a number of cell receptors, mainly the vascular endothelial growth factor receptor (VEGFR), the epidermal growth factor receptor (EGFR), and the RET-tyrosine kinase. The compound reported here, tert-butyl-4-((4-(4-bromo-2-fluorophenylamino)-6-methoxyquinazolin-7-yloxy)methyl)piperidine-1-carboxylate is the most important intermediate during production of Vandetanib.

Bond lengths and angles of the title compound are within normal ranges [7]. The crystal structure analysis of the title compound revealed that the 3 rings: piperidine ring (C16—C17—C18—C19—C20—N4), quinazoline ring (C2—N2—C1—N1—C4—C5—C6—C7—C8—C3) and 4-bromo-2-fluorophenyl ring (C9—C10—C11—C12—C13—C14), are not coplanar. The dihedral angle between the plane of the 4-bromo-2-fluorophenyl ring and the best plane of the piperidine ring is 33.9(2)°. The dihedral angle between the quinazolinyl moiety and the best plane of the piperidine ring is 32.7(2)°. In the crystal of the title compound, there are weak C—H⋯O, C—H⋯N and N—H⋯F intramolecular hydrogen bonds. There may be some π-π stacking interactions, as the centroid to centroid distance between the nearest rings is less than 5 Å.
