The title compound has been synthesized by the reaction of 1-(6-hydroxy-2-naphthyl)-1-ethanone (2) with p-toluenesulfonyl chloride. Its structure was determined by single crystal X-ray diffraction. 2-Acetylnaphthalen-6-yl 4-methylbenzosulfonate (3) crystallizes in the orthorhombic space group Pbca with a = 12.727(3) Å, b = 14.560 (3) Å, c = 17.688 (4) Å, V = 3277.8 (11) Å3, and Z = 8. The results demonstrate that the dihedral angle between the benzene ring and the naphthalene ring is 116.5∘, and the length (1.417 Å) of single C–O bond of 3 is longer than that of single C–O bond in the relative compounds.
