Supporting information


Comment top

Sulfonamides exhibit antibacterial (Misra et al., 1982), insulin-releasing (Maren, 1976), anti-inflammatory (Li et al., 1995) and antitumor (Yoshino et al., 1992) activities. The geometric parameters in the title compound agree with the reported values of similar structure (Ramachandran et al., 2008; Vennila et al., 2009).

The dihedral angle between the phenyl ring and naphthalene ring is 8.95 (8)°. The geometry around S1 atom is distorted from a regular tetrahedron [O1—S1—N1 = 107.09 (10) °; O2—S1—N1 = 105.66 (11)°; O1—S1—C11 = 108.25 (10)°]. The molecular structure is stabilized by weak intramolecular C—H···O and C—H···N interactions and the crystal packing is stabilized by a weak intermolecular C—H···O, C—H···Cl (Fig. 2) and ππ [Cg2···Cg4(-1 - x, 1 - y, -z) = 3.8782 (16) Å; Cg2-centroid of ring C1–C6; Cg4-centroid of C13–C18 ring] interactions.

The intermolecular C8—H8···Cl1 interaction generates 14-membered ring, with graph-set motif R22(14) and C16—H16···O2 interaction generates ten-membered ring, with graph-set motif R22(10).

Experimental top

1 g (3.6 mmol) of 5-bromo-2-chloro-benzyl-cyclopropyl-amine is dissolved in 20 ml of ethyl acetate. To the above mixture, 0.57 g (7.2 mmol) of pyridine is added with stirring and then 0.7 g (3 mmol) of naphthalene-2-sulfonyl chloride is added and heated to 50 °C for 6 h. The reaction mass is cooled to room temperature and 20 ml of water is added. The aqueous layer is separated. The ethyl acetate layer is washed twice with 10% sodium chloride solution and dried over 2 g of anhydrous sodium sulfate. The solvent is removed under vacuum and the crude product obtained is recrystallized from hexane–ethyl acetate mixture to get diffraction quality white crystals.

Refinement top

H atoms were positioned geometrically and refined using riding model with C—H = 0.93–0.98 Å and Uiso(H) = 1.2Ueq(C) for aryl and methine H atoms and Uiso(H) = 1.5Ueq(C) for methylene H atoms.
