Ethyl 1-[(4-acetyl-2-methoxyphenoxy)methyl]cyclopropane-1-carboxylate

Abstract top

In the title compound, C16H20O5, the dihedral angle between the planar rings, viz. benzene and cyclopropane, is 52.1 (2)°. Molecules are connected in the crystal via weak intermolecular C-H...O hydrogen bonds, forming chains in the [001] direction.

Comment top

The title compound, (I), is one of the most important intermediates in the synthesis of 7-[(1-aminocyclopropyl)methoxy]-N-(1H-indol-5-yl)-6-methoxyquinolin-4-amine, which has advantageous pharmacological properties and inhibits the activity of protein tyrosine kinases (Chen, 2008). We report here the crystal structure of (I).

All bond lengths and angles are within expected ranges. Both benzene and cyclopropane rings are planar, and make a dihedral angle of 52.1 (2)° (rings C3···C8 and C11···C13). Molecules are linked together via intermolecular C—H···O hydrogen bonds, which may be effective to the stabilization of the crystal structure.

Experimental top

The title compound was synthesized using a method similar to that reported recently (Chen, 2008). The crystals were obtained by evaporating the acetone slowly at room temperature for about 14 d.

Refinement top

H atoms were positioned geometrically, with C—H = 0.93 (aromatic), 0.96 (methyl) or 0.97 Å (methylene), and constrained to ride on their parent atoms, with Uiso(H) = xUeq(carrier C), where x = 1.5 for methyl groups and x = 1.2 otherwise. Methyl groups were allowed to rotate about their C—C bonds.
