Diethyl 2,2′-[(5-dimethyl­amino-1-naphth­yl)sulfonyl­imino]diacetate

In the title compound, C(20)H(26)N(2)O(6)S, the N atom of the dimethyl­amino group is displaced by 0.113 (2) Å from the plane of the naphthalene ring system. The two eth­oxy groups adopt zigzag conformations. In the crystal structure, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules, forming a three-dimensional network. Both ethyl groups are disordered over two sites with the ratios of refined occupancies being 0.857 (16):0.143 (16) and 0.517 (14):0.483 (14).
