tert-Butyl 2-{[5-(4-cyanophenyl)pyridin-3-yl]sulfonyl}acetate

Abstract

In the title compound, C18H18N2O4S, the dihedral angle between the aromatic rings is 33.71 (9)° and an intramolecular C—H...O hydrogen bond closes an S(6) ring. In the crystal, molecules are linked by C—H...O and C—H...N hydrogen bonds to generate a three-dimensional network. A very weak aromatic π–π stacking interction is also observed [centroid–centroid separation = 3.9524 (10) Å].
