In the title compound, C(24)H(22)ClNO(3), the dihedral angle between the naphthalene ring system and the chloro-phenyl ring is 67.44 (4)°. The pyrrolidine and dihydro-pyran rings exhibit envelope and half chair conformations, respectively. In the crystal structure, weak C-H⋯π inter-actions are observed.

Hexagonal mesoporous silica (SBA-15) was prepared and then functionalized by(3-mercaptopropyl)trimethoxysilane. The obtained 3-mercaptopropyl functionalized SBA-15 (SBA-Pr-SH) was then oxidized using H2O2 in methanol under an acidic condition to give sulfonic acid functionalized mesoporous silica (SBA-Pr-SO3H).
