RESUMO
In the title compound, C(19)H(13)NO(4)S, the mol-ecule is twisted at the S atom with a C-S-N-C torsion angle of -65.2â (2)° between the benzene ring and the -SO(2)-NH-C=O segment. The dihedral angle between the benzene and the naphtho-furan ring system is 83.3â (1)°. In the crystal, mol-ecules are linked by N-Hâ¯O hydrogen bonds into chains running along the c axis. An intra-molecular N-Hâ¯O(furan) inter-action is also observed.
