Abstract: The title compound, C₁₃H₁₃ClO₆S, contains two methoxycarbonyl groups in a cis arrangement, with a dihedral angle of 79.9 (1)° between the least-squares planes defined by the two methoxycarbonyl fragments. Weak van der Waals interactions between the molecules are effective in the molecular packing. This is the first X-ray structure reported for a tosylmaleate derivative which can be used as a pharmaceutical primary material.
