4-{[4-(3,5-Dimeth­oxy­benzamido)­phen­yl]sulfan­yl}-N-methyl­pyridine-2-carboxamide

There are two independent mol­ecules in the asymmetric unit of the title compound, C(22)H(21)N(3)O(4)S. The central benzene ring makes dihedral angles of 74.28 (6) and 68.84 (6)° with the pyridine and 3,5-dimeth­oxy­phenyl rings, respectively, in one molecule [86.66 (6) and 81.14 (6)° respectively, in the other]. Each of the mol­ecules forms a centrosymmetric dimer with another mol­ecule via pairs of inter­molecular N—H⋯O hydrogen bonds. These hydrogen bonds connect the N—H groups and the O atoms of the carbonyl groups next to the 3,5-dimeth­oxy­phenyl rings. Additional inter­molecular N—H⋯O inter­actions link the dimers in the crystal structure.
