Crystal structure of ethyl 2-(2-{1-[N-(4-bromophenyl)-2-oxo-2-phenylacetamido]-2-tert-butylamino-2-oxoethyl}-1H-pyrrol-1-yl)acetate

Abstract

In the title compound, C28H30BrN3O5, there is an intramolecular N—H...O hydrogen bond and an intramolecular C—H...O hydrogen bond, both forming S(9) ring motifs. The planes of the 4-bromophenyl ring and the phenyl ring are inclined to that of the pyrrole ring by 48.05 (12) and 77.45 (14)°, respectively, and to one another by 56.25 (12)°. In the crystal, molecules are linked via C—H...O hydrogen bonds and C—H...π interactions, forming slabs parallel to (10-1).
