tert-Butyl N-[2-(N-isobutyl-4-methoxy-benzenesulfonamido)ethyl]carbamate

The title compound, C18H30N2O5S, was synthesized by the reaction of tert-butyl 2-(isobutylamino) ethylcarbamate with pmethoxyphenylsulfonyl chloride. In the molecule, two intramolecular C-H center dot center dot center dot O hydrogen bonds are observed. In the crystal, molecules are linked by N-H center dot center dot center dot O hydrogen bonds involving the imino group N atom and the ester group O atom into chains running parallel to the b axis. The chains are further connected by C-H center dot center dot center dot O hydrogen bonds, forming layers parallel to the bc plane.
