N-(Phenyl-sulfon-yl)naphtho-[2,1-b]furan-1-carboxamide.
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 -65.2 (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 83.3 (1)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into chains running along the c axis. An intra-molecular N-H⋯O(furan) inter-action is also observed.
